Question

Which of the following statements is correct for an exothermic reaction?
Options
A The products have a lower enthalpy than the reactants.
Correct Answer
B The reaction absorbs heat from the surroundings.
C The enthalpy change (ΔH) is positive.
D The products are more stable, and ΔH is positive.
Correct Answer

Option A is the correct answer.

Detailed Explanation

In an exothermic reaction, heat is released to the surroundings, so the products have a lower enthalpy (potential energy) than the reactants, making ΔH negative.

Hint

Exo = out; heat exits the system.
