|Class 12 Chemistry Chemical Kinetics||Introduction|
The stream of chemistry that governs the rate of reactions along with their mechanisms is termed as Chemical kinetics derived from a Greek word meaning chemical movement.
Combination of two or more reactants to produce a new product is called reaction.
Elementary Reaction: The reaction that occurs in a single step to give the product is called an elementary reactions.
Complex reaction: The reactions that occur as a result of sequence of elementary reactions to give the product is called complex reactions.
