Vedclass · Answer

(C) . For a zero-order reaction,$t_{1/2} = \frac{[A]_0}{2K}$. As the concentration decreases,the half-life decreases. (Correct statement)$B$. If the order with respect to a reactant is zero,it will not affect the rate of reaction. (Correct statement)$C$. Order can be fractional,but molecularity is always a whole number and cannot be fractional. (Incorrect statement)$D$. For a zero-order reaction,the unit is $mol \ L^{-1} s^{-1}$,and for a second-order reaction,the unit is $mol^{-1} L s^{-1}$. (Correct statement)Thus,only statement $C$ is incorrect. The number of incorrect statements is $1$.
