The total energy of the reaction can be calculated by finding the difference between the energy of the reactants and the energy of the products.
Energy of reactants = 732 kJ/mol
Energy of products = 2(energy of XY)
Total bond energy of XY = 1256 kJ/mol
Therefore, energy of XY = 1256 kJ/mol รท 2 = 628 kJ/mol
Energy of products = 2(628 kJ/mol) = 1256 kJ/mol
Total energy of the reaction = Energy of products - Energy of reactants
= 1256 kJ/mol - 732 kJ/mol
= 524 kJ/mol
Therefore, the total energy of the reaction is 524 kJ/mol.
Energy of reactants = 732 kJ/mol

Therefore, energy of XY = 1256 kJ/mol รท 2 = 628 kJ/mol
Energy of products = 2(628 kJ/mol) = 1256 kJ/mol
Total energy of the reaction = Energy of products - Energy of reactants
= 1256 kJ/mol - 732 kJ/mol
= 524 kJ/mol
Therefore, the total energy of the reaction is 524 kJ/mol.
