Question

What is the molar enthalpy of reaction for the combustion of methane? The balanced chemical equation and the bond energies for the various bonds in the reactants and products are
CH4 (g) + 2 02 (g)= CO2 (g) + 2 H2O (g)


O=O =498 kJ/mol

C-O =358 kJ/mol

O-H = 463 kJ/mol

C=O =732 k/mol

C-H =413 kJ/mol

(a)+80 kJ/mole
(b)+668 kJ/mole
(c)-284 kJ/mole
(d)-668 kJ/mole​
