The unit of rate constant for a zero order reaction is, mol L − 1 s − 1, L mol − 1 s − 1, L 2 mol − 2 s − 1, s − 1

For zero order reaction, Rate = k [ Reactants ] ∘ ∴ Rate = k and unit of k = mol L − 1 s − 1

Options:

A $\mathrm{mol} \mathrm{L}^{-1} \mathrm{~s}^{-1}$
B $\mathrm{L} \mathrm{mol}^{-1} \mathrm{~s}^{-1}$
C $\mathrm{L}^{2} \mathrm{~mol}^{-2} \mathrm{~s}^{-1}$
D $\mathrm{s}^{-1}$

Solution:

The correct answer is: $\mathrm{mol} \mathrm{L}^{-1} \mathrm{~s}^{-1}$

For zero order reaction,
Rate $=k[\text { Reactants }]^{\circ}$
$\therefore$ Rate $=k$
and unit of $k=\operatorname{mol} \mathrm{L}^{-1} \mathrm{~s}^{-1}$
