In an exothermic reaction, the enthalpy change is negative. Which of the following is also true for an exothermic reaction?
2 answers:
<u>Answer: </u>The correct statement is the products have a lower potential energy than the reactants.
<u>Explanation:</u>
Exothermic reactions are defined as the reactions in which the enthalpy change of a reaction is negative.
Enthalpy of a reaction is determined by the equation:
As, the enthalpy change of the reaction is negative, which means that the potential energy of the products is less than the potential energy of the reactants.
Hence, the correct statement is the products have a lower potential energy than the reactants.
