MCQ
The unit of rate constant for a zero order reaction is
- ✓$mol\, L^{-1}\, s^{-1}$
- B$L \,mol^{-1} \,s^{-1}$
- C$L^2\, mol^{-2}\, s^{-1}$
- D$s^{-1}$
✓
Answer
Correct option: A.
$mol\, L^{-1}\, s^{-1}$
a
The rate law expression for the zero order reaction is Rate $= k [ A ]^0$
The rate law expression for the zero order reaction is Rate $= k [ A ]^0$
$mol\,L ^{-1}\, \sec ^{-1}= k \times\left( mol\,L ^{-1}\right)^0$
Unit of $k = mol\, L ^{-1}\, sec ^{-1}$
The unit of rate constant for a zero order reaction is $mol\, L ^{-1} \,s ^{-1}$.
