heat of reaction, the amount of heat that must be added or removed during a chemical reaction in order to keep all of the substances present at the same temperature. … If the heat of reaction is positive, the reaction is said to be endothermic; if negative, exothermic.
What is the definition of heat reaction?
Definition of heat of reaction : the heat evolved or absorbed during a chemical reaction taking place under conditions of constant temperature and of either constant volume or more often constant pressure especially : the quantity involved when gram equivalents of the substances enter into the reaction.
What causes a heat reaction?
It takes energy to break a chemical bond but energy is released when chemical bonds are formed. If more energy is released than consumed, then the chemical reaction evolves heat and is said to be exothermic. … Most reactions are exothermic. The amount of heat generated by a reaction can be quantified.
