Complete Question

.For the simple decomposition reaction: , the rate =  and k = . How long (in seconds) will it take for the concentration of AB to reach one-third of its initial concentration of ? Enter to 2 decimal places

The time it would take would be    

Explanation:

The given decomposition reaction is

Also  initial concentration of AB is    

         The rate constant is given as    

The objective of this solution is to obtain the time(t) it would take for concentration of AB to reach one third of its initial concentration

    Now the the concentration at time t is

                                f

Now this time is mathematically represented as

      substituting value

the answer is d.) potassium
