For the gas phase reaction 2SO2(g) + O2(g) º 2SO3(g); observed mole fractions for a certain equilibrium mixture at 1000 K and 1767 torr are 0.310, 0.250 and 0.440 respectively for the three gases. Deduce K0p and ΔG0 at this temperature if one assumes ideal gases. Calculate, also, the values of K0p and K0c at this temperature.
