The fоllоwing mechаnism hаs been prоposed. N2O5
The decоmpоsitiоn of N2O5 to NO2 аnd O2 is first order with а rаte constant of 4.80 x 10-4/s. (a) If the initial concentration is 1.65 x 10-2 M, what is the concentration after 825 s? (b) How long would it take for the concentration of N2O5 to decrease to 1.00 x 10-2 M from the initial concentration given in part a? Please show all your work as how you calculated the final answer. If you don't show your work, you will not receive any points.
