According to Le Chatelier's principle, what happens to the equilibrium of an exothermic reaction when the temperature is increased?
- A.Shifts to the forward direction
- B.Shifts to the backward direction
- C.No change occurs
- D.The reaction stops
Show correct answer & step-by-step solution
Correct answer: B — Shifts to the backward direction
Solution
- An exothermic reaction releases heat, represented as .
- Increasing the temperature adds heat to the system.
- Le Chatelier's principle states the system will shift to counteract the change.
- The system shifts to consume the added heat, which is the backward direction.
- Hence the answer is (B).
