For the water gas reaction c(g)+h_{2}o(g)=co(g)+h_{2}(g ) the standard Gibbs free energy for the reaction at 1000k is -8.1 k^{3} /mol. Calculate its Equlipriam constant. (R=8.314×10^{-3}k^{3}/k/mol).

Given:

Gibbs free energy ΔG^{0} = −8.1 kJ

= 8100 J

Temperature, T = 1000 K

Gas constant, R = 8.314 J/mol K

We know,

Equilibrium constant kp =
