Catalyst used in making \[{{H}_{2}}S{{O}_{4}}\] in contact process is:

A) \[{{V}_{2}}{{O}_{5}}\]                                   

B) \[F{{e}_{2}}{{O}_{3}}\]

C) \[C{{r}_{2}}{{O}_{3}}\]                  

D) \[Cr{{O}_{3}}\]

Correct Answer: A

Solution :

Even at \[400-{{500}^{o}}C\] the rate of reaction is very low. Therefore, to increase the reaction velocity a suitable catalyst is used. Now a days most of the sulphuric acid plants use \[{{V}_{2}}{{O}_{5}}\] as a catalyst.
