Assertion : In presence of +ve catalyst, activation energy & threshold energy decreases. Reason : Minimum energy required to permit a reaction is known as threshold energy.

Options

  1. AIf both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
  2. BIf both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark
  3. CIf Assertion is true statement but Reason is false, then mark (3).
  4. DIf both Assertion and Reason are false statements, then mark (4).

Correct answer

B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark

Step-by-step solution

Positive catalyst favours rate of reaction by decreasing activation energy and threshold energy. 2nd statement is a definition of threshold energy.
