Step 1
Rate law: Rate law are the mathematical expression used to show concentration of reactant and product that changes with time.
It can be represented as: Rate = K [A]a [B]b here A nd B are reacting species, a and b are stoichiometry coefficient.
Rate constant (k): It is the proportionality constant used to show direct relation between rate of reaction and concentration of reactant.
