Accepted Answer

The enthalpy of reaction (∆H°rxn) can be calculated using the following equation:
∆H°rxn = Σ∆Hf°(products) - Σ∆Hf°(reactants)
Plugging in the given values:
∆H°rxn = [(-1258) + 2(-167)] - [(-555) + 2(-207)]
∆H°rxn = -1634 - (-971)
∆H°rxn = -663 kJ/mol
Therefore, the enthalpy of reaction for the given reaction is -663 kJ/mol.
