For a reaction $A + B \to \text{Products}$,the rate law is: $\text{Rate} = k[A][B]^{3/2}$. Can the reaction be an elementary reaction? Explain.
(N/A) An elementary reaction is a single-step process where the order of the reaction is equal to the sum of the stoichiometric coefficients of the reactants.
For an elementary reaction,the order must be an integer (usually $1, 2, \text{or } 3$).
In the given rate law,$\text{Rate} = k[A]^1[B]^{3/2}$,the overall order of the reaction is $1 + 3/2 = 5/2 = 2.5$.
Since the order of the reaction is fractional,it cannot be an elementary reaction.
