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 \[t=\frac{2.303\times 10}{0.693}\times \log 10\] \[=33\min \]You need to login to perform this action.
