Assertion : The overall order of the reaction is the sum of the exponents of all the reactants in the rate expression. Reason : There are many higher order reactions.

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

C. If assertion is true but reason is false

Step-by-step solution

Reactions of higher order are rare because chances for larger number of molecules to come simultaneously for collision are less.
