Rate law expression of a reaction is:
\[
\text { Rate }=\mathrm{k}[\mathrm{A}]^{2 / 3}[\mathrm{~B}]
\]
Which of the following are incorrect about the corresponding reaction?
(1) Order of reaction \( =\frac{2}{3}+1=\frac{5}{3} \)
(2) Unit of rate constant \( =\mathrm{L}^{2 / 3} \mathrm{~mol}^{-2 / 3} \mathrm{sec}^{-1} \)
(3) Unit of rate constant \( =\mathrm{atm}^{-2 / 3} \mathrm{sec}^{-1} \)
(4) Unit of rate of reaction \( =\mathrm{mol} \mathrm{L}^{-1} \mathrm{sec}^{-1} \)
