Graph of exothermic and endothermic reaction

Accepted Answer

An exothermic reaction is a chemical reaction that releases energy in the form of heat. An endothermic reaction is a chemical reaction that requires energy in the form of heat in order to occur. The graph of an exothermic reaction shows a decrease in enthalpy (energy) over time, while the graph of an endothermic reaction shows an increase in enthalpy over time.
