The Correct Option is A

Solution and Explanation

The rate constant’s unit depends on the reaction order. For example, a first-order reaction has units of sec⁻¹, while second- and higher-order reactions involve units of concentration (mol/L) raised to varying powers. Thus, ordering is (C) < (A) < (B) < (D).
