Answer to Question #47842 in Physical Chemistry for Erin Grannemann

Question

At 298 K the standard enthalpy of combustion of solid L-valine (C5H11NO2 (s)) to give CO2 (g), H2O (liq) and N2 (g) is ΔcombH° = –2911 kJ/mol. Calculate ΔrxH° and ΔrxU° at 298 K for the following reaction.
C5H11NO2 (s) + HCHO (g) + 4 H2 (g) → 3 C2H5OH (liq) + NH3 (g)
