Assertion : Many endothermic reactions that are not spontaneous at room temperature become spontaneous at high temperature. Reason : Entropy of the system increases with increase in temperature.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion.

Step-by-step solution

The factor TΔST \Delta S increases with increase in temperature.
