(a) Suppose you are studying the decomposition kinetics of a chemical that proceeds as a second-order process. If you start with an initial concentraion of 0.132 M for this substance and its concentration is found to be 0.048 M after 215 minutes have passed, what is the rate constant for this reaction? Report it in units of M-¹.min-¹. QUESTION 14 Continued from the previous problem (b) How much time (in min) will have elapsed when the reaction has completed two half-lives?

(a) Suppose you are studying the decomposition kinetics of a chemical that proceeds as a second-order process. If you start with an initial
concentraion of 0.132 M for this substance and its concentration is found to be 0.048 M after 215 minutes have passed, what is the rate
constant for this reaction? Report it in units of M-1-min-¹.
