A) \[{{s}^{-1}}\]
B) \[\text{mol}\,\text{L}{{\text{s}}^{-1}}\]
C) \[mol\,{{L}^{-1}}{{s}^{-1}}\]
D) no unit
Correct Answer: C
Solution :
For nth order of reaction a general formula for the unit of rate constant is \[{{\left( \frac{\text{mole}}{\text{litre}} \right)}^{1-n}}\times {{\sec }^{-1}}\] \[\because \]For zero order reaction,\[n=0\] \[\therefore \]Unit of rate constant for zero order reaction is mole \[\text{litr}{{\text{e}}^{-1}}{{\sec }^{-1}}\]or \[\text{mol}\,{{L}^{-1}}{{S}^{-1}}.\]
