Which of the following statements is not true for an exothermic reaction?a. The temp. of the surroundings increasesb. The temp of the reaction systems increasesc. The products have a higher heat content than the reactantsd. Heat passes from the reaction system to the surroundingse. The enthalpy change for the reaction is negative

The products have a higher heat content than the reactants

Explanation:

Recall that the change in enthalpy for a reaction is obtained from

∆Hreaction= enthalpy of products - enthalpy of reactants

For an exothermic reaction, enthalpy of reactants > enthalpy of products, hence ∆Hreaction is negative.

This implies that the heat content of reactants is greater than that of products for an exothermic reaction. Hence the option selected in the answer is false as written.
