Consider the gas phase reaction N2O42NO2 occurring in an isothermal and isobaric reactor maintained at 298 K and 1.0 bar. The standard Gibbs energy change of the reaction at 298 K is = 5253 J mol−1. The standard states are those of pure ideal gases at 1.0 bar. The equilibrium mixture in the reactor behaves as in the ideal gas. The value of the universal gas constant is 8.314 Jmol−1 K−1. If one mole of pure N2O4 is initially charged to the reactor, the fraction of N2O4that decomposes into NO2 at equilibrium is
