Hydrogen peroxide decomposes to yield water and oxygen. The decomposition is first order with a rate constant at 46°C of 1.6 × 10-4 s-1. Calculate the partial pressure of the oxygen produced from 1.25 L of a 0.750 M H2O2 solution at 46°C over a period of 24.0 hours if the gas is collected in a 13.0 L container.

Please show all work! Thanks in advance!
