Question

Define order of a reaction. Give one example.

Answer 1

The order of reaction with respect to a particular reactant is the exponent to which the concentration term of that reactant, in the rate law is raised. The overall order of the reaction is the sum of the exponents to which the concentration terms in the rate law are raised. For example, consider the reaction $aA+bB\to$ products. The order of the reaction with respect to the reactants A and B is a and b respectively. The overall order of the reaction is $a+b$
