A) \[2.88\times {{10}^{-3}}{{s}^{-1}}\]
B) \[2.72\times {{10}^{-3}}{{s}^{-1}}\]
C) \[1.44\times {{10}^{-3}}{{s}^{-1}}\]
D) \[1.44{{s}^{-1}}\]
Correct Answer: C
Solution :
We know that \[{{t}_{1/2}}=\frac{0.693}{k}\] Or \[k=\frac{0.693}{{{t}_{1/2}}}=\frac{0.693}{480}\] \[=1.44\times {{10}^{-3}}{{s}^{-1}}\]
