Question

Which of the following according to Le-Chatelier’s principle is correct?

• A. Increase in temperature favours the endothermic reaction
• B. Increase in temperature favours the exothermic reaction
• C. Increase in pressure shifts the equilibrium in that side in which number of gaseous moles increases
• D. All of the above are true

Hint:

Temperature increase always favours endothermic reactions.

Answer 1

The Correct Option is A

Step 1: According to Le-Chatelier’s principle, the system opposes the applied change.
Step 2: Increase in temperature favours the endothermic direction.
Step 3: Increase in pressure favours the side with fewer gaseous moles, hence (C) is incorrect.
