In a 4L closed glass container at 505K, the equilibrium partial pressure for the reaction 2NO2(g)--> N2O4(g) are 0.0686 atm for NO2(g) and 1.250 atm for N2O4(g). What pressure of NO2(g) must be added to this equilibrium system in order for the pressure of N2O4(g) to become 1.3atm when equilibrium is again reached at 505K?
