The rate constant for a particular reaction that is 1st-order in N2O5 is 0.525 min–1. How much time will it take for the concentration of N2O5 to decrease to one-third its initial concentration? Make sure you pick an answer with the correct units. (Hint: Fora 1st-order reaction, the amount of time it takes to reduce a reactant's concentration to one-third is independent of the initial concentration of reactant.)
