For a given set of reactions based on energy considerations the reaction which occurs more readily has to be identified. Concept Introduction: Δ H ° refers to change in enthalpy. Change in enthalpy in a reaction and bond energy (BE) are related as, Δ H r x n ° = ΣBE(reactants)-ΣBE(products) A reaction is exothermic reaction when heat is released during the reaction. A reaction is endothermic reaction when heat is absorbed during the reaction. Endothermic reaction has Δ H ° value in positive sign. Exothermic reaction has Δ H ° value in negative sign.
