Options
A ΔH is positive.
B The system gains heat.
C The surroundings gain heat.
Correct Answer
D The enthalpy of products is higher than reactants.
Correct Answer

Option C is the correct answer.

Detailed Explanation

In an exothermic reaction, heat is released by the system into the surroundings. Therefore, the surroundings gain heat. This corresponds to a negative ΔH, where the enthalpy of the products is lower than that of the reactants.

Hint

The prefix 'exo-' means outward. Where does the heat go?
