The area of physical chemistry that deals with comprehending the speeds of chemical processes is known as chemical kinetics, sometimes known as reaction kinetics. In contrast, chemical thermodynamics addresses the direction in which a reaction takes place but does not address the pace of the process. Chemical kinetics is the study of how experimental circumstances affect a chemical reaction's rate and reveal details about its mechanism and transition stages. It also involves the development of mathematical models that may be used to represent the properties of a chemical process. Chemists and chemical engineers may better comprehend and explain chemical processes including food degradation, microbial development, stratospheric ozone decomposition, and the oxidation of organic compounds by using the mathematical models that describe chemical reaction kinetics. The mathematical models that depict chemical reactions Chemical engineers and chemists can use kinetics to better comprehend and characterise chemical processes including food deterioration, microbial development, stratospheric ozone breakdown, and the chemistry of biological systems. In order to maximise product production, effectively segregate goods, and get rid of by-products that are bad for the environment, these models may also be utilised in the design or modification of chemical reactors. Kinetic models can be used, for instance, to determine the temperature and pressure at which the largest yield of heavy hydrocarbons into gasoline will happen when heavy hydrocarbons are catalytically cracked into gasoline and light gas.
