A) \[1.118\]
B) \[0.1118\]
C) \[18.11\]
D) \[11.18\]
Correct Answer: D
Solution :
\[k=\frac{2.303}{t}\log \frac{a}{a-x}\] \[\log \frac{a}{a-x}=\frac{kt}{2.303}\] \[=\frac{2.2\times {{10}^{-5}}\times 60\times 90}{2.303}\] \[=0.0516\] Hence \[\frac{a}{a-x}=1.127\] \[\frac{a-x}{a}=0.887\] or \[1-\frac{x}{a}=0.887\] \[\frac{x}{a}=0.113=11.3%\]You need to login to perform this action.
