A factory uses a reversible reaction between gases to manufacture a solvent.
The table shows data for the reaction at three operating temperatures.
| Temperature (∘C^\circ\mathrm{C}∘C) | Relative rate | Solvent in the mixture at equilibrium (%) | Heating energy needed (GJ per tonne of solvent) |
|---|---|---|---|
| 320 | 2 | 64 | 1.8 |
| 360 | 6 | 51 | 2.2 |
| 400 | 15 | 35 | 2.9 |
The factory is considering using a temperature of 360 ∘C360\,^\circ\mathrm{C}360∘C rather than 320 ∘C320\,^\circ\mathrm{C}320∘C or 400 ∘C400\,^\circ\mathrm{C}400∘C.
Evaluate this choice. Use data from the table in your answer.
