A) 31.3 min
B) 32.3 min
C) 33.3 min
D) 34.3 min
Correct Answer: C
Solution :
: Decay constant, \[k=\frac{2.303}{t}\log \frac{a}{a-x}\] \[k=\frac{2.303}{t}\log \frac{a}{a/8}\] \[k=\frac{2.303}{100}\log 8\] \[k=0.021\,{{\min }^{-1}}\] \[{{t}_{1/2}}=\frac{0.693}{0.021}=33\,\min \]You need to login to perform this action.
