| Vol. of \[{{N}_{2}}\]in cc | Times (min) |
| 6.25 | 10 |
| 9.00 | 15 |
| 11.40 | 20 |
| 13.65 | 25 |
| 35.65 | Infinity |
A) zero
B) one
C) two
D) three
Correct Answer: B
Solution :
For first order reaction, \[k=\frac{2.303}{t}\log \frac{a}{a-x}\] \[a\propto {{V}_{\infty }}(=35.05)\]and \[x\propto {{V}_{t}}.\] Constant values of fc calculated for different times, shows first order reaction.
