Exothermic change definition

WebEnthalpy change (∆H) is the amount of heat energy transferred during a chemical reaction at constant pressure. It is also measured in J mol-1 or kJ mol-1. Reactions can be endothermic or exothermic. Endothermic reactions absorb heat energy. They have a positive enthalpy change and decrease the temperature of the surroundings. Weba decrease in the internal energy of the system (an exothermic change, as discussed in the previous chapter on thermochemistry) an increased dispersal of matter in the system (which indicates an increase in the entropy of the system, as you will learn about in the later chapter on thermodynamics)
