Question

Match the items of List I and List II:
Reactions
A. Decomposition of N2O on hot Pt.
B. Hydrolysis of ester by acid
C. Alkaline hydrolysis of ester
D. Reduction of FeCl3 by SnCl2

Unit of rate constant
(I) mol^-2L^2Time^-2
(II) mol L^-1Time^-1
(III) mol^-1L Time^-1
(IV) Time^-1

Prashant Kotian · Accepted Answer

Correct answer: D. Sol. Decomposition of N2O on hot platinum is zero order reaction so unit rate constant = 1 1 mol L Time  . Acidic hydrolysis of ester is first order reaction, so unit of rate constant = 1 Time. Alkaline hydrolysis of ester is second order reaction, so unit of rate constant = 1 1 mol L Time  . Reduction of 3 FeCl by 2 SnCl , is third order reaction, so unit of rate constant = 2 2 1 mol L Time  .
