In the preparation of sulphuric acid, $ {{V}_{2}}{{O}_{5}} $ is used in the reaction which is
In the preparation of sulphuric acid, $ {{V}_{2}}{{O}_{5}} $ is used in the reaction which is
Updated On: Jul 28, 2022
- $S + O _{2} \rightarrow SO _{2}$
- $SO _{2}+ H _{2} O \rightarrow H _{2} SO _{4}$
- $2 SO _{2}+ O _{2} \rightarrow 2 SO _{3}$
- None of these
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In contact process of manufacture of $H _{2} SO _{4}$ first of all $SO _{2}$ is oxidised to $SO _{3}$ by atmospheric oxygen in presence of $V _{2} O _{5}$ as a catalyst.
$2SO_2 + O_2 {->[V_2O_5]} 2SO_3$

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
