Assertion : When temperature becomes ( ) then the value of rate constant is maximum. Reason : A is also known as maximum rate constant.

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

( aligned & K = Ae ^ - E _ a / RT & ~T & E _ a / RT 0 & e ^0=1 & ~K = A & [ ~K increases as temperature increases. ] & [ K _ = A = maximum rate constant ] aligned )
