chemical kinetics – area of chemistry dealing with speeds/rates of reactions. rates of reactions affected by four factors concentrations of reactants; temperature at which reaction occurs; presence of a catalyst; surface area of solid or liquid reactants and/or catalysts
What are Chemical Kinetics? Chemical Kinetics. Kinetics – how fast does a reaction proceed? Thermodynamics – does a reaction take place? Reaction speed: measured by the change in concentration with time. Important factors which affect rates of reactions: reactant concentration. temperature. action of catalysts. surface area.
Chemical Kinetics Class 12 Notes Chemistry Chapter 4 1. Chemical kinetics is the branch of chemistry which deals with the study of rates (or fastness) of chemical reactions, the factors affecting it and the mechanism by which the reactions proceed.

Chemical kinetics, also called reaction kinetics, helps us understand the rates of reactions and how it is influenced by certain conditions. It further helps to gather and analyse information about the mechanism of the reaction and define the characteristics of a chemical reaction.
In thinking about chemical reactions, rate matters. This lecture provides an introduction to kinetics and shows one of the coolest reactions known: the oscillating clock reaction. Watch as colors change quickly as different steps in the reaction become spontaneous.
In Unit V, we consider the speed, or rate, of chemical reactions. Thermodynamics tells us if a particular reaction will be spontaneous, but not how fast it will occur. Thus, both thermodynamics and kinetics are necessary for understanding chemical reactions.
