Expert Answer

Step 1

The rate of a given reaction can be defined as the speed at which the conversion of reactants into the products takes place.

Step 2

The term first order reaction is defined for those reactions which proceed at a rate that has a linear dependence on the concentration of only one reactant.

Step 3

The integrated rate law equation for a first-order reaction is as follows:
