Options
- AIt accelerates the conversion of H 2 SO 4 to SO 3
- BIt promotes the decomposition of SO 3 to SO 2
- CIt increases the reaction rate in the conversion of SO 2 to SO 3
- DIt acts as an acid catalyst
Correct answer
C. It increases the reaction rate in the conversion of SO 2 to SO 3
Step-by-step solution
In the Contact Process, the catalyst V 2 O 5 increases the reaction rate in the conversion of SO 2 to SO 3 .
