Answer to Question #35894 in Physical Chemistry for Guy

Question

At 298 K the standard enthalpy of combustion of solid alanine (NH2CH(CH3)COOH (s)) to give CO2 (g), H2O (liq) and N2 (g) is ΔcombH° = -1618 kJ/mol and the standard enthalpy of formation of liquid methylamine (CH3NH2(liq)) is ΔfH° = -47.3 kJ/mol. Calculate ΔrxH° and ΔrxU° at 298 K for the following reaction.
NH2CH(CH3)COOH (s) + 2H2 (g) → CH3NH2 (liq) + CH4 (g) + HCO2H (liq)
