The following data were obtained during the first order decomposition of 2A(g) → B(g) + C(s) at a constant volume and at a particular temperature.
| Sr. No. | Time | Total pressure in Pascal |
|---|---|---|
| 1. | At the end of 10 min | 300 |
| 2. | After completion | 200 |
The rate constant in min–1 is
