Using Hess's Law to calculate net reaction enthalpy 3/5 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) + 3 H,(g) CH,OH(#) + H,O(1) AH=-131, kJ In the second step, methanol reacts to form dimethyl ether and water: 2 CH,OH(1) → CH,OCH,(g) + H,0(1) AH=8. kJ Calculate the net change in enthalpy for the formation of one mole of dimethyl ether from carbon dioxide and hydrogen from these reactions.
