Which of the following statements are correct about the kinetics of this reaction? (i) The rate of reaction depends on the concentration of only (b). (ii) The rate of reaction depends on the concentration of both (a) and (b). (iii) Molecularity of reaction is one. (iv) Molecularity of reaction is two.

Option (i) and (iii) are the answers.

The SN1 mechanism is used in the given reaction. The production of carbocation is a gradual process in the SN1 mechanism. As a result, the pace of reaction is determined by the concentration of the reactant (ii). As a result, the rate of reaction is determined only by the concentration of (ii), and the molecularity of the reaction is one.
