Dinitrogen pentoxide, N2O5, undergoes first-order decomposition in chloroform solvent to yield NO2 and O2. The rate constant

Question:

Dinitrogen pentoxide, N2O5, undergoes first-order decomposition in chloroform solvent to yield NO2 and O2. The rate constant at 45oC is 6.2 × 104/min. Calculate the volume of O2 obtained from the reaction of 1.00 mol N2O5 at 45oC and 770 mmHg after 20.0 hr.
