Chemical reactions can result in energy being released (exothermic) or energy being absorbed (endothermic). We can use the law of conservation of energy to determine how that energy is transferred between a system and its surroundings. Energy diagrams visually represent potential energy changes during a reaction, providing quantitative information about the bond-breaking and bond-forming process.
