1. For the gas phase decomposition of phosphine at 120 C 4 PH 3 (g) P 4 (g) + 6 H 2 (g) the following
1. For the gas phase decomposition of phosphine at 120 C 4 PH3(g)P4(g) + 6 H2(g) the following data have been obtained:
| [PH3], M | 2.0410-2 | 1.0310-2 | 5.1910-3 | 2.6210-3 |
| time, s | 0 | 38.0 | 76.0 | 114 |
The average rate of disappearance of PH3 over the time period from t = 76.0 s to t = 114 s is M s-1.
2. For the decomposition of nitrosyl bromide at 10 C 2 NOBr2 NO + Br2 the following data have been obtained:
| [NOBr], M | 0.162 | 8.4910-2 | 5.7610-2 | 3.9710-2 |
| time, s | 0 | 7.00 | 14.0 | 21.0 |
The average rate of disappearance of NOBr over the time period from t = 7.00 s to t = 14.0 s is M s-1.
