Question
Nitrosyl chloride is produced from the reaction of nitrogen monoxide and chlorine:
2NO(g) + Cl2(g) → 2NOCl(g)
The following initial rates at a given temperature were obtained for the concentrations listed below.
| Experiment | Initial Rate (mol·L-1·h-1) | [NO]0(mol·L-1) | [Cl2]0(mol·L-1) |
| 1 | 2.21 | 0.25 | 0.25 |
| 2 | 19.89 | 0.75 | 0.25 |
