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
Correct answer is D
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.
