What is the difference between a first-order reaction and a second-order reaction?

A first order reaction will have an overall order of one, the sum of all the exponents will be 1. A second order reaction will have an overall order of 2, the sum of all the exponents will be 2.

In a first order reaction, doubling the concentration of the reactant will double the rate of the reaction. In a second order reaction, doubling the concentration of the reactant will quadruple the rate of the reaction. Hope this helps!

The order of a reaction refers to the index, or exponent, to which its concentration term in the rate equation is raised.
