Interpretation: The energy associated with reversing reactions needs to be explained.
Concept introduction: The energy in a system is a combination of potential and kinetic energy. The energy of motion is the kinetic energy and the stored energy within a physical energy is termed as potential energy.

Answer to Problem 1TAI
Energy in a chemical system is in the form of either potential energy or kinetic energy.
Explanation of Solution
In chemical processes energy is conserved. This means that the net energy exchange in a forward process is equal and opposite to the net energy exchange in reverse process. If a forward reaction is exothermic, the reverse reaction is endothermic. Energy in a chemical system is in the form of either potential energy or kinetic energy. When a substance burns, some potential energy of the substances converted to kinetic energy
Law of conservation of mass is followed in every chemical change.
