Open in App
Solution
The correct option is B Vanadium pentoxide
A catalyst is a substance which alters the rate of the chemical reaction without itself undergoing any chemical change. There are two types of catalysts:
(a) Positive catalyst: Catalyst which increases the rate of the reaction.
(b) Negative catalyst: Catalyst which decreases the rate of the reaction.
Vanadium pentoxide is a positive catalyst used in the industrial preparation of sulphuric acid. The reaction for the industrial preparation of sulphuric acid is:
2SO2(g)+O2(g)V2O5→2SO3(g)+Heat
