Which of the following is the key step in the manufacture of sulphuric acid ?
A.
Burning of sulphur or sulphide ores in air to generate $$S{O_2}.$$
B.
Conversion of $$S{O_2}$$ to $$S{O_3}$$ by the reaction with oxygen in presence of catalyst.
C.
Absorption of $$S{O_3}$$ in $${H_2}S{O_4}$$ to give oleum.
D.
Both (B) and (C).
Answer :
Conversion of $$S{O_2}$$ to $$S{O_3}$$ by the reaction with oxygen in presence of catalyst.
Solution :
The key step in the manufacture of $${H_2}S{O_4}$$ is catalytic oxidation of $$S{O_2}$$ with $${O_2}$$ to give $$S{O_3}$$ in presence of $${V_2}{O_5}.$$
