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
