Question

Assertion :The endothermic reactions are favoured at lower temperature and the exothermic reactions are favoured at higher temperature. Reason: When a system in equilibrium is disturbed by changing the temperature, it will tend to adjust itself so as to overcome the effect of change.
  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Assertion is incorrect but Reason is correct

A
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
B
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
C
Assertion is correct but Reason is incorrect
D
Assertion is incorrect but Reason is correct
Solution
Verified by Toppr

The correct option is D Assertion is incorrect but Reason is correct
Le Chatelier's principle states that "if a system in equilibrium is subjected to a change of concentration, temperature or pressure, the equilibrium shifts in a direction so as to undo the effect of the change imposed."
