Dinitrogen pentoxide, N2O5, decomposes by first-order process with a rate constant of 3.7 x 10-5 s-1 at 298K.

a) What is the half-life in hours for the decomposition of N2O5 at 298 K?

b) If the concentration of N2O5 starts at 2.33 x 10-2 M, what will the concentration be after 2 hours?

c) How many minutes will it take for the concentration of N2O5 to decrease from 0.0233M to 0.0176M?
