Chemical Kinetics Question 303
Question: Which of the following reactions is not of the first order-
Options:
A) Inversion of sucrose in the presence of acid
B) Acid-catalyzed hydrolysis of ethyl acetate
C) Hydrolysis of tertiary butyl halide using alkali
D) Oxidation of $ {I^{-}} $ ion by $ S_2O_8^{2-} $ ion
Show Answer
Answer:
Correct Answer: D
Solution:
[d] It is a second order reaction, first order both w.r.t $ S_2O_8^{2-} $ and $ {I^{-}} $ .
$ \therefore r=k[S_2O_8^{2-}][{I^{-}}] $ All other options are of first order reaction.
