Energy From Fossil Fuels Bond Making and Bond Breaking. During chemical reactions, energy is either released to the environment (exothermic reaction) or absorbed from the environment (endothermic reaction). During chemical reactions, bonds are broken in the reactants and new ones are made in the products. In this approach we make use of the fact that the average kinetic energy of the molecules can be expressed in terms of the kinetic temperature. In addition, we know that conservation of energy in this case involves just the balancing of kinetic energy and gravitational potential energy so long as we treat the atmosphere as an ideal gas.
