Given the thermodynamic data in the table below, calculate the equilibrium constant (Keq) for the reaction:
2SO2 (g) + O2 → (g) 2SO3 (g)
Substance ΔHf° (kJ/mol) ΔS° (J/mol K)
SO2(g) -297 249
O2(g) 0 205
SO3(g) -395 256

Again we first need to use ΔG°= ΔH° - T ΔS° with T in units of Kelvin
And then second ΔG°= - RT ln ...
