Assertion : The kinetics of the reaction
(m A+n B+p C \rightarrow m^{\prime} X+n^{\prime} Y+p^{\prime} Z)
obeys the rate expression as -
(\frac{d x}{d t}=k[A]^m[B]^n)
Reason : The rate of reaction does not depend upon the concentration of .
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion.
Step-by-step solution
Rate expression (\frac{d x}{d t}=k[A]^m[B]^n) shows that the total order of reactions is as the rate of reaction is independent of concentration of , i.e, the order with respect to is zero. This is the reason that does not figure in the rate expression.
