The heat of reaction for a chemical reaction can be calculated by finding the sum of the bond energies of the products and subtracting that from the sum of the bond energies of the reactants: heat of reaction==sum of the energy for the bonds broken ā sum of the energy for the bonds formedsum of reactant bond energies ā sum of product bond energies when calculating the sum of the bond energies, each bond in the reaction must be accounted for. for example, ch4 is a reagent with a coefficient of 1 in the reaction. there are four cāh bonds in methane and one methane molecule per reaction, for a total of four cāh bonds on the reactant side. all four bonds must be accounted for when finding the sum of the bond energies for the reactants. calculate the heat of reaction using the average bond dissociation energies given in the introduction and your answer to part b for the reaction ch4 + 2o2 ā co2 + 2h2o express your answer in kilojoules per mole to three significant figures.
