Determine whether the reaction is energetically favorable at room temperature. Assume that AS O. Calculate the gas phase enthalpy change using bond dissociation enthalpies at 25 C from the table below.

Include the algebraic siga and speeifly units, e.g. 45 kil/mol. Calculate to the nearest single ehergy unit. kJ/mol. Calculate to the nearest single energy unit b. Is the reaction exothermic or endothermic
