Dimethyl ether, a useful organic solvent, is prepared in two steps. In the first step, carbon dioxide and hydrogen react to form methanol and water: CO2(g) + 3H2(g) → CH3OH (l) + H2O(l) =ΔH−131.kJ In the second step, methanol reacts to form dimethyl ether and water: 2CH3OH (l) → CH3OCH3(g) + H2O (l) =ΔH8.kJ Calculate the net change in enthalpy for the formation of one mole of dimethyl ether from carbon dioxide and hydrogen from these reactions.
