Expert Solution
Step 1Introduction
This question belongs to chemical kinetics.
We are given k = 0.206 s-1
Initial concentration( Ao) of NH3 = 1.45 M
We will find the concentration of NH3 after 3.10 sec
Let A is the concentration of NH3 after time t and k is the rate constant for 1st order reaction.
