In the production of sulfuric acid by the Contact process, the following exothermic reaction takes place:
2\text{SO}_2(\text{g}) + \text{O}_2(\text{g}) \xrightarrow{\text{V}_2\text{O}_5,\, 420\,^\circ\text{C},\, 2\text{ atm}} 2\text{SO}_3(\text{g})
Which of the following conditions would favour the forward reaction?
I. Low pressure
II. Excess oxygen
III. Low temperature
- (A)I only
- (B)I and II only
- (C)II and III only
- (D)I, II and III
