Identify a type of order of reaction that its unit of rate constant is mol dm ⁻³ s ⁻¹ from the following.

Step-by-step solution

The general formula for the unit of the rate constant k for an n -th order reaction is given by ( concentration )^ 1-n time ⁻¹ . Using the standard units of concentration as mol dm ⁻³ and time as s , the unit of k becomes ( mol dm ⁻³)^ 1-n s ⁻¹ . The given unit of the rate constant is mol dm ⁻³ s ⁻¹ . Comparing the powers of the concentration term, we get: 1 - n = 1 n = 0 Therefore, the reaction is a zero-order reaction. Answer: Zero-order reaction
