Decreases
Explanation:
The molecules lose potential energy during chemical reactions.
In a chemical reactions, bonds are broken for new ones to be formed. The process of breaking and forming bonds diminishes the potential energy of a bond.
Potential energy is the energy at rest in a body.
In chemicals, potential energy is constituted by the chemical energy stored within the bonds.
When chemical reactions occur, the energy is released often in the form of heat energy. There is always a decrease in potential energy when chemicals reacts together.
