Glycine, c2h5o2n, is important for biological energy. the combustion reaction of glycine is described by the following thermochemical equation. 4c2h5o2n(s) + 9o2(g) → 8co2(g) + 10h2o(l) + 2n2(g) δh°rxn = –3896 kj/molwhat is the standard enthalpy of formation of solid glycine? –51.90 kj/mol–527.5 kj/mol–974.0 kj/mol–1502 kj/mol–2476 kj/mol

-537.25 kJ/mol is the standard enthalpy of formation of solid glycine.

Explanation:

Standard enthalpy of formation of oxygen gas=

Standard enthalpy of formation of carbon dioxide=

Standard enthalpy of formation of water =

Standard enthalpy of formation of nitrogen gas=

Standard enthalpy of formation of glycine =

Enthalpy of the reaction =

=

On rearranging :

-537.25 kJ/mol is the standard enthalpy of formation of solid glycine.

the answer is true. hope it .
