# Problem: Which one of the following sets of units is appropriate for a second-order rate constant?A. s-1B. mol L-1 s-1C. L mol-1 s-1D. mol2 L-2 s-1E. L2 mol-2 s-1

###### FREE Expert Solution

To determine the unit of k for a second-order reaction, we will use the following equation:

$\overline{){\mathbf{k}}{\mathbf{=}}{{\mathbf{M}}}^{\mathbf{-}\mathbf{n}\mathbf{+}\mathbf{1}}{\mathbf{·}}{{\mathbf{t}}}^{\mathbf{-}\mathbf{1}}}$

n = overall order of the reaction
n = order with respect to A
