Sulfur trioxide is manufactured using a reversible reaction. The forward reaction is exothermic. Two operating temperatures are compared while all other conditions remain unchanged.
The values in each results row are listed in no particular order.
| Quantity | Values |
|---|---|
| Operating temperature in °C | 420 and 480 |
