Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria.
Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate. Chemical kinetics includes investigations of how experimental conditions influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that also can describe the characteristics of a chemical reaction.
The American Chemical Society (ACS) is a scientific society based in the United States that supports scientific inquiry in the field of chemistry. Founded in 1876 at New York University, the ACS currently has more than 155,000 members at all degree levels and in all fields of chemistry, chemical engineering, and related fields. It is one of the world's largest scientific societies by membership. The ACS is a 501(c)(3) non-profit organization and holds a congressional charter under Title 36 of the United States Code. Its headquarters are located in Washington, D.C., and it has a large concentration of staff in Columbus, Ohio.
The International Chemistry Olympiad (IChO) is an annual academic competition for high school students. It is one of the International Science Olympiads. The first IChO was held in Prague, Czechoslovakia, in 1968. The event has been held every year since then, with the exception of 1971. The delegations that attended the first events were mostly countries of the former Eastern bloc and it was not until 1980, the 12th annual International Chemistry Olympiad, that the event was held outside of the bloc in Austria. Up to 4 students for each national team compete around July in both a theoretical and an experimental sections, with about half of the participants being awarded medals.
In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs.
Chemical physics is a branch of physics that studies chemical processes from a physical point of view. It focuses on understanding the physical properties and behavior of chemical systems, using principles from both physics and chemistry. This field investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics.
Joint Entrance Examination – Advanced (JEE-Advanced), is an academic examination held annually in India that tests the skills and knowledge of the applicants in physics, chemistry and maths. It is organised by one of the seven zonal IITs under the guidance of the Joint Admission Board (JAB) on a round-robin rotation pattern for the qualifying candidates of the JEE-Main. It used to be the sole prerequisite for admission to the Indian Institutes of Technology bachelor's programs before the introduction of UCEED, Online B.S. and Olympiad entries, but seats through these new mediums are very low.
Advanced Placement (AP) Chemistry is a course and examination offered by the College Board as a part of the Advanced Placement Program to give American and Canadian high school students the opportunity to demonstrate their abilities and earn college-level credits at certain colleges and universities. The AP Chemistry Exam has the lowest test participation rate out of all AP Courses, with around half of AP Chemistry students taking the exam.

The United States Physics Olympiad (USAPhO) is a high school physics competition run by the American Association of Physics Teachers and the American Institute of Physics to select the team to represent the United States at the International Physics Olympiad (IPhO). The team is selected through a series of exams testing their problem solving abilities. The top 20 finalists are invited to a rigorous study camp at the University of Maryland to prepare for the IPhO.
Donna J. Nelson is an American chemist and professor of chemistry at the University of Oklahoma. Nelson specializes in organic chemistry, which she both researches and teaches. Nelson served as a science advisor to the AMC television show Breaking Bad. She was the 2016 President of the American Chemical Society (ACS) with her presidential activities focusing on and guided by communities in chemistry. Nelson's research focused on five primary topics, generally categorized in two areas, Scientific Research and America's Scientific Readiness. Within Scientific Research, Nelson's topics have been on mechanistic patterns in alkene addition reactions and on Single-Walled Carbon Nanotube (SWCNT) functionalization and analysis, yielding the first COSY NMR spectrum of covalently functionalized SWCNTs in solution. Under America's Scientific Readiness, she focuses on science education and impacting science by considering its communities; this includes classroom innovations and correcting organic chemistry textbook inaccuracies, on ethnic and gender diversity among highly ranked science departments of research universities, and on improving the image and presentation of science and scientists to the public.
The Indian National Physics Olympiad is the second stage of the five-stage Olympiad programme for Physics in India. It ultimately leads to the selection in the International Physics Olympiad.
This article describes the selection process, by country, for entrance into the International Mathematical Olympiad.
The Willard Gibbs Award, presented by the Chicago Section of the American Chemical Society, was established in 1910 by William A. Converse (1862–1940), a former Chairman and Secretary of the Chicago Section of the society and named for Professor Josiah Willard Gibbs (1839–1903) of Yale University. Gibbs, whose formulation of the Phase Rule founded a new science, is considered by many to be the only American-born scientist whose discoveries are as fundamental in nature as those of Newton and Galileo.
General chemistry is offered by colleges and universities as an introductory level chemistry course usually taken by students during their first year. The course is usually run with a concurrent lab section that gives students an opportunity to experience a laboratory environment and carry out experiments with the material learned in the course. These labs can consist of acid-base titrations, kinetics, equilibrium reactions, and electrochemical reactions. Chemistry majors as well as students across STEM majors such as biology, biochemistry, biomedicine, physics, and engineering are usually required to complete one year of general chemistry as well.
The ICFESexamination, or Saber 11, is a high school exit examination administered annually in grade 11 in Colombian high schools. The exam is standardized, similar to the SAT and ACT examinations taken by high school students in the United States. The purpose of the exam is to evaluate students' aptitude in five subjects: critical reading, mathematics, social studies, science, and English. Each exam question has four multiple-choice answers, except for the English section which provides between three and eight possible answers for each question.
Chinese Chemistry Olympiad is an annual academic competition held by Chinese Chemical Society. CAS changed its official Chinese name in February 2014, though its English translation remains the same.
National Science Talent Contest or NSTC is an extension of the National Physics Talent Contest launched by PIEAS in 1995 on the directive of the then President of Pakistan. The purpose of the NSTC is to inspire the youth of the Nation to opt for careers in science, and mathematics and to prepare young students for participation in International Science Olympiads in Physics, Biology, Chemistry and Mathematics.
Korean Chemistry Olympiad(KChO,한국화학올림피아드) is a chemistry olympiad held by Korean Chemical Society (KCS). It is also one of the Korean Science Olympiad. The top four contestants of the KChO can join the International Chemistry Olympiad(IChO).
The British Physics Olympiad (BPhO) is a series of ten competitions in the study of physics for students in years 11–13 in the United Kingdom.
