Question

reaction the rate law expression is represented as follows:
Rate = k [A][B]1/2
i)Interpret whether the reaction is elementary or complex. Give reason to support your answer.
ii)Write the units of rate constant for this reaction if concentration of A and B is expressed in moles/L​

Answer 1

Reaction is a complex reaction.

Order of reaction is 1.5.

Molecularity cannot be 1.5, it has no meaning for this reaction. The reaction occurs

in steps, so it is a complex reaction.

(ii)units of k are mol-1/2L
