A) \[{{t}_{1/2}}\propto {{C}^{-1}}\]
B) \[{{t}_{1/2}}\propto C\]
C) \[{{t}_{1/2}}\propto {{C}^{0}}\]
D) \[{{t}_{1/2}}\propto {{C}^{1/2}}\]
Correct Answer: C
Solution :
The relation between half-life period and initial concentration for a nth order reaction is given by. \[{{t}_{1/2}}\propto \frac{1}{{{C}^{n-1}}}\] For first order rear don\[(n=1)\] \[{{t}_{1/2}}\propto \frac{1}{{{C}^{1-1}}}\] or \[{{t}_{1/2}}\propto {{C}^{0}}\]
