An exothermic reaction is allowed to reach equilibrium; if heat energy is then removed, the equilibrium will shift
Correct answer: A. Towards the product side
- A. Towards the product side
- B. toward the reactant side.
- C. Towards the middle.
- D. None of these
Explanation
When heat is removed, the temperature of the system is lowered, and that favors the exothermic reaction, which, according to Le Chatelier's principle, will shift towards the product side.

About Le Chatelier's Principle
Le Chatelier's principle predicts how an equilibrium responds when concentration, pressure or temperature changes. Questions apply it to reversible reactions, identify the direction of shift and distinguish genuine equilibrium changes from the effect of a catalyst, which changes the rate of reaching equilibrium but not its position.
