What do you understand by the order of a reaction?

What is order of a reaction?

Answer 1

1. According to the rate law, a reaction’s rate is determined by a specific power of the reactant concentration. 
2. The order of reaction is typically used to describe the experimentally observed relationship between the reaction rate and reactant concentration.
3. The power to which the concentration term of a particular reactant in the rate law is raised is called the order of reaction with respect to that reactant, and the sum of all the powers to which all the concentration terms in the rate law are raised to express the observed rate of reaction is called the overall order of reaction.
