Consider the gaseous reaction
A2 + B2 → 2AB
The following data was obtained for the above reaction
| [A2]0 | [B2]0 | Initial rate of formation of AB (mol L-1 s-1) |
| 0.1 M | 0.1 M | 2.5 × 10-4 |
| 0.2 M | 0.1 M | 5.0 × 10-4 |
| 0.2 M | 0.2 M | 1.0 × 10-3 |
The value of rate constant for the above reaction is
1
1.25 × 10-2
2
1.25 × 10-3
3
2.5 × 10-2
4
2.5 × 10-1
