Gaseous dinitrogen pentaoxide decomposes into oxygen and nitrogen dioxide. If we start with a partial pressure of 300 torr for the N2O5 and zero for the products, the equilibrium pressure of the N2O5 will be 150 torr. However, if the original pressure of N2O5 is now 125 torr, what will the partial pressure of NO2 be when the total pressure is 179 torr?
