Use the thermodynamic data below to answer the following questions regarding this chemical reaction:

CH4(g) + H2O(g) ®3 H2(g) + CO(g)

DeltafG°[CH4(g)] = -50.8 kJ/mol, DeltafG°[H2O(g)] = -228.6 kJ/mol, DeltafG°[H2(g)] = 0.0 kJ/mol, and DfG°[CO(g)] = -137.2 kJ/mol;

a. Calculate the standard net Gibbs free energy change for the reaction as written.

b. Calculate the equilibrium constant in terms of Kp andKc. (Note: DfG°'s given above relate to Kp, not Kc.

(R = 8.314 J/mol K = 0.08206 L atm/mol K)

c. Estimate the mol fraction of carbon monoxide (CO) at equilibrium
