Two solutions, reactant A and reactant B, react to form a soluble salt and a gas.
The reaction is carried out under two different sets of conditions in Experiment P and Experiment Q, as shown in the table below.
| Condition | Experiment P | Experiment Q |
|---|---|---|
| Temperature (°C°\text{C}°C) | 45 | 25 |
| Concentration of A (mol/dm3\text{mol/dm}^3mol/dm3) | 0.5 | 1.5 |
Explain why it is not possible to predict whether the rate of Experiment Q will be faster or slower than the rate of Experiment P.
