Calculate ΔH° for the following reaction using the given bond dissociation energies.
CH4 + 2(O2) ----> CO2 + 2(H2O)
Delta H for following bonds:
O-O...142 kJ/mol
H-O...459 kJ/mol
C-H...411 kJ/mol
C=O...799 kJ/mol
O=O...498 kJ/mol
C-O...358 kJ/mol
I do know its exothermic however my solutions are by no means detrimental! My products are all the time better than the reactants. The deltaH from the carbon dioxide is already so massive as a result of the double bond between C and O right? How is it possible? Please lend a hand!!
