A) 0.383 min
B) 23.1 min
C) 8.73 min
D) 7.53 min
Correct Answer: B
Solution :
[b] For a first order reaction, \[A\to \] Products \[r=k[A]\,or\,k=\frac{r}{[A]}\] \[\Rightarrow k=\frac{1.5\times {{10}^{-2}}}{0.5}=3\times {{10}^{-2}}\] Further, \[{{t}_{1/2}}=\frac{0.693}{k}=\frac{0.693}{3\times {{10}^{-2}}}=23.1\]You need to login to perform this action.
