Match List I with List II :

List I (Order of reaction)List II (Unit of rate constant)
A. Zero orderI. $mol^{-1} L s^{-1}$
B. First orderII. $mol^{-2} L^2 s^{-1}$
C. Second orderIII. $s^{-1}$
D. Third orderIV. $mol L^{-1} s^{-1}$

Choose the correct answer from the options given below :

This question was previously asked in
NEET UG Re-Exam 2026 Question Paper (21-Jun-2026)
The correct answer is

A-IV, B-III, C-I, D-II

Zero order reaction → mol L⁻¹ s⁻¹
First order reaction → s⁻¹
Second order reaction → mol⁻¹ L s⁻¹
Third order reaction → mol⁻² L² s⁻¹

So the correct matching is :

A → IV
B → III
C → I
D → II
