A) \[\frac{{{[A]}_{0}}}{2k}\]
B) \[\frac{In\,2}{k}\]
C) \[\frac{1}{k{{[A]}_{0}}}\]
D) \[\frac{In\,2}{{{[A]}_{0}}k}\]
Correct Answer: A
Solution :
For zero order reaction, Rate constant \[k=\frac{{{[A]}_{0}}-{{[A]}_{t}}}{t}\] Here,\[{{A}_{0}}=\]initial concentration of reactant \[{{A}_{t}}=\]concentration of reactant after t time. If half-life period is\[{{t}_{1/2}}.\]Initial amount\[({{A}_{0}})\] will become half. \[{{A}_{t}}=\frac{{{[A]}_{0}}}{2},\] \[k=\frac{{{[A]}_{0}}-\frac{1}{2}{{[A]}_{0}}}{{{t}_{1/2}}}\] \[\because \] \[{{t}_{1/2}}=\frac{{{}_{0}}}{2k}\]You need to login to perform this action.
