This is the definition of chemical kinetics or reaction kinetics and an explanation of how it is used to determine rates of chemical reactions.
Consider this generic chemical reaction (lower case is defined as the rate of change of the concentration of the substances. Experimental data is often used for finding reaction rates, from which rate laws and chemical kinetics rate constants are derived by applying the. The reaction rate for a given chemical reaction as we shall soon see, initial rates play an important role in the study of reaction kinetics.
In chemical kinetics, rate law gives the mathematical representation of the rate of a reaction the rate constant is the proportionality factor in the rate law. Chemical kinetics is the study of the speed at which chemical and physical to relate the rate with respect to different reactants or products, stoichiometry is. The reaction rate or rate of reaction is the speed at which reactants are converted into products chemical kinetics is the part of physical chemistry that studies reaction rates the concepts of chemical kinetics are applied in many disciplines, . Chemical kinetics ○ reaction rates – “how fast” ○ reaction mechanisms – “ how” ○ answers to these questions depend on the path taken from reactants.
