Question

Name the catalyst which helps in the conversion of sulphur dioxide to sulphur trioxide?

Answer 1

1. The reaction of conversion of sulfur dioxide to sulfur trioxide is catalyzed by the catalyst, vanadium pentaoxide, and the reaction is-
2. ${\mathrm{SO}}_2\left(\mathrm{g}\right)\stackrel{{\mathrm{V}}_2{\mathrm{O}}_5}{\rightleftharpoons }{\mathrm{SO}}_3\left(\mathrm{g}\right)$
3. Hence, the catalyst is Vanadium pentoxide(${\mathrm{V}}_2{\mathrm{O}}_5$) or platinum($\mathrm{Pt}$).
