The overall reaction: C(s) + H2O(g) → CO(g) + H2(g)

The mechanism:

1. C(s) + O2(g) → CO2(g)                        ΔH1 = -393.5 kJ
 2. 2 CO(s) + O2(g) → 2 CO2(g)              ΔH2 = -566.0 kJ
 3. 2 H2(g) + O2(g) → 2 H2O(g)               ΔH3 = -483.6 kJ

Calculate the ΔHrnx for the following reaction C(s) + H2O(g) → CO(g) + H2(g)

Use the following reactions and given ΔH's

C(s) + O2(g) → CO2(g) Δh = -393.5 kJ
2CO(s) + O2(g) → 2CO2(g) Δh = -566.0 kJ
2H2(g) + O2(g) → 2H2O(g) Δh = -483.6 kJ
