Question

Name the catalyst in the given case and write the chemical equation for

Action of sulphur dioxide gas with oxygen:

Answer 1

• Vanadium pentoxide is used as a catalyst in the process of sulphur dioxide gas with oxygen.
• Here sulphur trioxide is formed.
• $\underset{\mathrm{sulphur}\mathrm{dioxide}}{\underset{}{2{\mathrm{SO}}_2\left(\mathrm{g}\right)}}+\underset{\mathrm{oxygen}}{\underset{}{{\mathrm{O}}_2\left(\mathrm{g}\right)}}\stackrel{{\mathrm{V}}_2{\mathrm{O}}_5}{\to }\underset{\mathrm{sulphur}\mathrm{trioxide}}{\underset{}{2{\mathrm{SO}}_3\left(\mathrm{g}\right)}}$
