What can be used to estimate the energy change of a chemical reaction?

Correct Answer: bond energies
isoenergies
bond magnitudes
chemical energy

Explanation: Bond energies can be used to estimate the energy change of a chemical reaction. When bonds are broken in the reactants, the energy change for this process is endothermic. When bonds are formed in the products, the energy change for this process is exothermic. We combine the positive energy change with the negative energy change to estimate the overall energy change of the reaction. For example, in.
