Assertion : In rate law,unlike in the expression for equilibrium constants,the exponents for concentrations do not necessarily match the stoichiometric coefficients.
Reason : It is the mechanism and not the balanced chemical equation for the overall change that governs the reaction rate.

  • A
    $A$. If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • B
    $B$. If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • C
    $C$. If the Assertion is correct but Reason is incorrect.
  • D
    $D$. If both the Assertion and Reason are incorrect.
