Q74 / 180 · AIIMS 2010 · Chemistry

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.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion
  • Correct answer
    C
    If assertion is true but reason is false
  • D
    If both assertion and reason are false.

Solution

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

Hence, the correct answer is option: 'C'.
