(10-12) Water gas, a mixture of H2 and CO, is a fuel made by reacting steam
with red-hot coke: H2O + C --> CO + H2. Find the following:
deltaHf (CO) = -110.5 kJ/mol ; deltas (CO) = 197.9 J/K mol
deltaHf (H2) = 0 kJ/mol ; deltas (H2) = 131 J/K mol
deltaHf (H20) = -241.8 kJ/mol ; deltas (H20) = 188.7 J/K mol
deltaHf (C) = 0 kJ/mol ; deltas (C) = 5.69 J/K mol
