Chemical reactions that release energy often occur spontaneously. Chemical
reactions that absorb energy will not occur without energy.
We can calculate the total energy change during a chemical reaction as. ∆E rec =
∆E product ... Describe the Role of Energy in Chemical Reactions. Back to Top.

When matter undergoes transformations that change its chemical and physical
properties then that transformation was brought about by a chemical reaction.
