$mol \cdot L^{- 1} \cdot \min^{- 1}$

${mol}^{2} \cdot L^{- 2} \cdot \min^{- 1}$

$L \cdot {mol}^{- 1} \cdot min^{- 1}$

$L^{2} \cdot {mol}^{- 2} \cdot \min^{- 1}$

answer is C.

Detailed Solution

The rate constant based on the total reaction order.

It unit for a zero-order reaction is in m/s, and for a first-order reaction are 1/s,. The units of it for second-order reaction are 1/(m·s).

For the given case, rate constant units is $L \cdot {mol}^{- 1} \cdot min^{- 1}$
