For an exothermic reactionH of the products is less than H of the reactantsH of the products is more than H of the reactantsH of the products is equal to H of the reactantsΔH is always positive
Solution
For an exothermic reaction, the enthalpy (H) of the products is less than the enthalpy (H) of the reactants. This is because energy is released during an exothermic reaction, which means the system loses energy. This loss of energy results in the products having a lower enthalpy than the reactants.
The change in enthalpy (ΔH) for an exothermic reaction is negative. This is because ΔH is calculated as the enthalpy of the products minus the enthalpy of the reactants (ΔH = Hproducts - Hreactants). Since the enthalpy of the products is less than the enthalpy of the reactants, ΔH will be a negative value.
So, the correct answer is "H of the products is less than H of the reactants".
