Calculate the enthalpy for the following reaction: N₂ + O₂ → 2 NO Given the following bond dissociation energies: N₂ = 226 kcal/mol,O2 = 199 kcal/mol and NO = 145 kcal/mol.

Quizplus · Accepted Answer

The enthalpy change for the reaction can be calculated using bond dissociation energies: ΔH = (Bonds broken) - (Bonds formed). For N2 + O2 → 2NO, ΔH = (226 + 199) - (2 * 145) = 425 - 290 = 135 kcal/mol.
