Question

CH4(g)+2O2(g)->CO2(g)+2H2O(g) AH° < 0 Which of the following statements must be true for the combustion of CH4(g), represented by the equation above? 4CHE65 The bond dissociation energy between O atoms in O2 is greater than the sum of the bond dissociation energies of the two O - H bonds in H2O. The sum of the bond dissociation energies of the product molecules is equal to the sum of the bond dissociation energies of the reactant molecules. More bonds are formed in the products than are broken in the reactants. The sum of the bond dissociation energies of the product molecules is greater than the sum of the bond dissociation energies of the reactant molecules.
