A) 3.0 h
B) 360 min
C) 4.5 h
D) 600 min
Correct Answer: B
Solution :
\[\lambda =\frac{0.693}{{{t}_{1/2}}}\] \[=\frac{0.693}{1.5}{{h}^{-1}}=0.462\,{{h}^{-1}}\] \[{{N}_{0}}=1;\,N=\frac{1}{16}\] \[t=\frac{2.303}{\lambda };\log \frac{{{N}_{0}}}{N}\] \[=\frac{2.303}{0.462}\log 16\] \[=6\text{ }h=360\text{ }\min \]You need to login to perform this action.
