Expert Answer:

For the reaction A Products, which follows first order kinetics, the rate of the reaction is proportional to the concentration of A raised to power 1. i.e.,
 
 
Integration of the differential equation gives In [A] = - kt + constant
 
At t = 0, [A] = [A]o
ln [A]o = constant
 
On substitution, the integrated equation is transformed to
 
 
 
The rate constant k1, of a first order reaction can be determined from the expression, The integrated rate equation can also be written in the form,
 
 
rate constant of a first order reaction
