The hydrolysis of ester in alkaline medium is a (A) First order reaction with molecularity 1 (B) Second order reaction with molecularity >2 (C) First order reaction with molecularity 2 (D) Second order reaction with molecularity 2

A reaction proceeds in three stages, The first stage is a slow second order reaction, the second stage is fast and of first order, the third stage is fast and is a third order reaction. The overall order of the reaction is :

Assertion (A) : The rate constant of a pseudo unimolecular reaction has the units of a second order reaction. Reason (R ): A pseudo unimolecular reaction is a reaction of second order in whiich one of the reactant is present in large excess.

At a certain temperature, the first order rate constant k_(1) is found to be smaller than the second order rate constant k_(2) . If E_(a)(1) of the first order reaction is greater than E_(a)(2) of the second order reaction, then as temperature is raised:

If 50% of a reaction occurs in 100 second and 75% of the reaction occurs in 200 second, the order of this reaction is :
