SO\(_2\) + O\(_2\) → 2SO\(_3\)
In the reaction above, the most suitable catalyst is?
- chromium(vi)oxide
- iron(iii)oxide
- copper(i)oxide
-
vanadium(v)oxide
The correct answer is: D
Explanation
During the Contact Process for manufacturing sulfuric acid, sulfur dioxide has to be converted into sulfur trioxide, which is done by passing sulfur dioxide and oxygen over a solid vanadium(V) oxide catalyst.
