Question:

Dinitrogen pentoxide (N2O5) decomposes in chloroform as a solvent to yield NO2 and O2. The decomposition is first order with a rate constant at 45oC of 1.0 × 10-5 s-1. Calculate the partial pressure of O2 produced from 1.00 L of 0.600 M N2O5 solution at over a period of 20.0 hr if the gas is collected in a 10.0-L container. (Assume that the products do not dissolve in chloroform.)
