A) \[tim{{e}^{-1}}\]
B) \[mol\,\,{{L}^{-1}}\,{{s}^{-1}}\]
C) \[L\,\,mo{{l}^{-1}}\,{{s}^{-1}}\]
D) \[L\,\,mo{{l}^{-1}}\,{{s}^{-1}}\]
Correct Answer: B
Solution :
Key Idea: For zero order reaction Rate \[=k\,{{[conc.]}^{0}}\] \[\therefore \] k = Rate or \[k=\frac{change\text{ }in\text{ }concentration}{time\text{ }taken}=\frac{mol/L}{s}\] \[\therefore \] Units of are \[mol\,{{L}^{-1}}{{s}^{-1}}\]
