For a reaction $A+B\rightarrow$ products, the rate law is — Rate $= k [A][B]^{3/2}$ . Can the reaction be an elementary reaction? Explain.

Answers (1)

Given that the rate of reaction is $k[A][B]^{\frac{3}{2}}$

Order = $1+\frac{3}{2}=\frac{5}{2}$

The order of elementary reaction cannot be fractional.

Hence, this indicates that the reaction is not an elementary reaction.
