Dinitrogen pentoxide decomposes in chloroform as a solvent to yield nitrogen dioxide and oxygen gas. The decomposition is first order with a rate constant of 1.0 x 10-5 s-1 at 45 degrees Celsius. Calculate the partial pressure of oxygen produced from 1.00L of 0.600M dinitrogen pentoxide solution at 45 degrees celsius over a period of 20.0hours if the gas is collected in 10.0L container. (Assume that the products do not dissolve in chloroform.)
