Question

Calculate the magnitude of resonance energy of CO2 from the following data (in kJ/mol).Bond energies: C=O = 539.0, O=O = 498.0Heat of sublimation of C(s) = 718.0Heat of combustion of C(s) = −393.0

Accepted Answer

$C(s) + O_{2}(g) ightarrow CO_{2}(g);\Delta H = - 393	ext{ kJ}$Now, $( - 393) = \lbrack 718 + 498brack - 2 	imes 539 - |R.E.|_{CO_{2}}$$	herefore|R.E.|_{CO_{2}} = 531	ext{ kJ/mol}$
