Question #62924

Answer 1

When steam is passed over red hot coke (C), it (`H_2O`) gets reduced hydrogen `H_2` and carbon is oxidized to `CO` producing a gas mixture of `CO(g)` and `H_2(g)`,known as water gas.

`C(s)("red hot") +H_2O(g)-> CO(g) + H_2(g)`

`Delta H=+131"kJ/mol"->"endothermic reaction"`
