To calculate the ΔH°rxn: ΔH°rxn = ΔH°f (products) - ΔH°f (reactants)
Balanced Reaction: C(s) + H2O(g)→ CO(g) + H2(g)
Reactants ΔH°f (kJ/mol) @ 298 K (values found in books or on the internet)
C(s) (graphite) 0 (natural state)
Water gas, a mixture of H2 and CO, is an important industrial fuel produced by the reaction of steam with red hot coke, essentially pure carbon: C(s) + H2O(g) ⟶ CO(g) + H2(g).
Assuming that coke has the same enthalpy of formation as graphite, calculate ΔH°298 for this reaction.
