Using the average bond dissociation enthalpies(BE) given, estimate the standard molar heat of reaction of the gas-phase reaction of hydrogen peroxide with methanol to yield formaldehyde and water:
HOOH(g)+ H3COH(g)? H2CO(g)+ 2 H2O(g)
BE (in kJ/mol): C?C (347); C?H (413); C=O (745); O?O (204); O?H (467); C?O (358)
