Professor PC Thomas Classes · Answer

(d) 
$\begin{aligned} & 	ext { Rate of reaction }=K[	ext { conc. }]^n \ & \qquad \begin{aligned} K & =\frac{	ext { Rate }}{[	ext { conc. }]^n}=\frac{M \mathrm{~s}^{-1}}{M^n}=\frac{\mathrm{mol} \mathrm{L}^{-1} \mathrm{~s}^{-1}}{\mathrm{~mol}^n \mathrm{~L}^{-n}} \ & =\mathrm{mol}^{1-n} \mathrm{~L}^{n-1} \mathrm{~s}^{-1}\end{aligned}\end{aligned}$
