Which of the following statements about an exothermic reaction is correct?
Answer Details
An exothermic reaction is a type of chemical reaction in which energy is released from the reaction system into the surroundings. Hence, the correct statement about an exothermic reaction is that the products have less heat content than reactants. This means that the energy released during the reaction is given off to the surroundings, and the enthalpy change for the reaction is negative. In contrast, an endothermic reaction is a reaction that absorbs energy from the surroundings, and has a positive enthalpy change.
