JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics
Reaction \(\mathrm{A}(\mathrm{g}) \rightarrow 2 \mathrm{~B}(\mathrm{~g})+\mathrm{C}(\mathrm{g})\) is a first order reaction. It was started with pure A
| t / min | Pressure of system at time t / mm Hg |
| 10 | 160 |
| ∞ | 240 |
Which of the following option is incorrect?
- A Initial pressure of A is 80 mm Hg
- B The reaction never goes to completion
- C Rate constant of the reaction is \(1.693 \mathrm{~min}^{-1}\)
- D Partial pressure of A after 10 minute is 40 mm Hg
Answer & Solution
Correct Answer
(C) Rate constant of the reaction is \(1.693 \mathrm{~min}^{-1}\)
