A) \[1.484\times {{10}^{3}}{{s}^{-1}}\]
B) \[6.7\times {{10}^{-4}}{{s}^{-1}}\]
C) \[6.7\times {{10}^{3}}{{s}^{-1}}\]
D) None of these
Correct Answer: B
Solution :
\[{{N}_{0}}=1,\,N=\frac{1}{128},\]\[t=2h=2\times 60\times 60\,s\] \[\lambda =\frac{2.303}{t}\log \frac{{{N}_{O}}}{N}\] \[\lambda =\frac{2.303}{2\times 60\times 60}\log \frac{1}{1/128}\] \[\lambda =6.7\times {{10}^{-4}}{{s}^{-1}}\]You need to login to perform this action.
