A) 20 min
B) 33 min
C) 15 min
D) 25 min
Correct Answer: B
Solution :
\[X(g)\xrightarrow[{}]{{}}Y(g)+Z(g)\] The reaction is a first order reaction. Hence \[k=\frac{0.693}{{{t}_{1/2}}}=\frac{2.303}{t}\log \frac{a}{a-x}\] \[\therefore \] \[\frac{0.693}{10}=\frac{2.303}{t}\log \frac{a}{a/10}\] Or \[t=\frac{2.303\times 10}{0.693}\times \log 10\] \[=33\text{ }min.\]You need to login to perform this action.
