💡 Solution & Explanation

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  .
