Glycine, C2H5O2N, is important for biological energy. The combustion reaction of glycine is given by the equation
4C2H5O2N(s) + 9O2(g) →8CO2(g) + 10H2O(l) + 2N2(g) ΔH°rxn = –3857 kJ/mol
Given that DH°f[CO2(g)] = –393.5 kJ/mol and ΔH°f[H2O(l)] = –285.8 kJ/mol, calculate the enthalpy of formation of glycine.
(A) –537.2 kJ/mol
(B) –268.2 kJ/mol
(C) 2,149 kJ/mol
(D) –3,178 kJ/mol
(E) –964 kJ/mol
(A) –537.2 kJ/mol
