Heat of combustion `DeltaH^(@)` for `C(s),H_(2)(g)` and `CH_(4)(g)` are `94, -68` and `-213Kcal//mol` . Then `DeltaH^(@)` for `C(s)+2H_(2)(g)rarrDeltaCH_(4)(g)` is

Heat of combustion DeltaH^(@) for C(s),H_(2)(g) and CH_(4)(g) are -94, -68 and -213Kcal//mol . Then DeltaH^(@) for C(s)+2H_(2)(g)rarrCH_(4)(g) is

Heat of combustion of C(s), H_2(g) and CH_4 (g) respectively are -94, -68 and -213 kcal/mol, then deltaH for the reacton [C(s) +2H_2(g) → CH_4(g)] is

Heat of formation of CO_(2)(g), H_(2)O(l) and CH_(4)(g) are -94.0, -68.4 and -17.9 kcal respectively. The heat of combustion of methane is

The heat of formation of C_(2)H_(5)OH(l) is -66Kcal//mol . The heat of combustion of CH_(3)OCH_(3)(g) is -348Kcal//mol , DeltaH_(f) for H_(2)O and CO_(2) are -68Kcal//mol and -94Kcal//mol . Respectively. Then, the DeltaH for the isomerisation reaction C_(2)H_(5)OH(l)rarrCH_(3)OCH_(3)(g) , and DeltaE for the same are at T=25^(@)C
