The concentration of R in the reaction R P was measured as a function of time and the following data is obtained:
| [R] (molar) | 1.0 | 0.75 | 0.40 | 0.10 |
|---|---|---|---|---|
| t (min.) | 0.0 | 0.05 | 0.12 | 0.18 |
The order of the reaction is

Answer and worked solution
Official answer: 0
Rates over each interval.
- 0 to 0.05 min: M min⁻¹;
- 0.05 to 0.12 min: M min⁻¹;
- 0.12 to 0.18 min: M min⁻¹.
The concentration falls linearly with time: the rate does not depend on [R]. The reaction is zero order.
