Identify the following reactions are exothermic or endothermic. Concept Introduction: In exothermic process, the energy of the system decreases and the energy of the surrounding increase. In endothermic process the energy of the system increases and the energy of the surrounding decrease.
Identify the following reactions are exothermic or endothermic. Concept Introduction: In exothermic process, the energy of the system decreases and the energy of the surrounding increase. In endothermic process the energy of the system increases and the energy of the surrounding decrease.
Solution Summary: The author explains that in exothermic processes, the energy of the system decreases and the surrounding increase, while in endothermitic processes it increases and reduces.
