Exothermic reaction chemistry definition
WebIn an exothermic chemical reaction, reactants have higher potential energy than products, and the enthalpy of the reaction is negative, -ΔH. (Energy is released to the surroundings) In an endothermic chemical reaction, products have more potential energy than reactants, and the enthalpy of the reactions is positive, +ΔH. (Energy is absorbed ...
