Question

For which of the following reactions, the units of rate constant and rate of reaction are same ?

• A. First order reaction
• B. Second order reaction
• C. Third order reaction
• D. Zero order reaction

Answer 1

The correct option is D Zero order reaction

For zero order,
R = k[A]
Unit of rate = mol $L^{-1}{t}^{-1}$
Unit of zero order = mol $L^{-1}{t}^{-1}$
