A reaction is first order and it takes 324 minutes for the reaction to be 50.0% complete. How long will it take for the reaction to be 85.0% complete at the same temperature?
2. N2O5 decomposes to N2O4 and O2 and the reaction is first order in N2O5 with a specific rate constant of 6.22 x 10^ -4 sec^-1 at 45 C. What will be the initial rate of formation of oxygen if the concentration of N2O5 is 0.100 M?
