In the first order "A -> products" reaction, initially [A] = 0.816 M, after 16.0 minutes it is [A] = 0.632 M. rate constant , what is the value of k ?

It is a simple question
Initial concentration ,time and final concentrations are given.
Use first order integrated rate law and plug in the given values in the equation.
