The equation for an industrial process is shown. C(s) + H2O(g) → CO(g) + H2(g) ΔH = +131 kJ / mol Which row is correct?

1. Athe oxidising agent is C(s); the reducing agent is H2O(g); the reaction is endothermic
2. Bthe oxidising agent is C(s); the reducing agent is H2O(g); the reaction is exothermic
3. Cthe oxidising agent is H2O(g); the reducing agent is C(s); the reaction is endothermic
4. Dthe oxidising agent is H2O(g); the reducing agent is C(s); the reaction is exothermic
