A) \[0.75/k\]
B) \[0.69/k\]
C) \[0.29/k\]
D) \[0.10/k\]
Correct Answer: C
Solution :
\[{{t}_{1/4}}=\frac{2.303}{k}\log \frac{1}{3/4}=\frac{2.303}{k}\log \frac{4}{3}\] \[=\frac{2.303}{k}(\log 4-\log 3)=\frac{2.303}{k}(2\log 2-\log 3)\] \[=\frac{2.303}{k}(2\times 0.301-0.4771)=\frac{0.29}{k}\]You need to login to perform this action.
