Question

The catalyst used in contact process is:

• A. $A{l}_2{O}_3$
• B. $C{r}_2{O}_3$
• C. $V_2{O}_3$
• D. $Mn{O}_2$

Answer 1

The correct option is C $V_2{O}_3$

The contact process is the method to produce sulfuric acid in the high concentrations needed for industrial processes. In this processs vanadium(V) oxide, Vanadium(III) oxide ($V_2{O}_5,V_2{O}_3$) is preferred as catalyst.

Hence option C is correct.
