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
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.
