Q. Contact process is used for the manufacture of sulphuric acid. Which of the following statement(s) is correct for this process?

$V_{2} O_{5}$ is used for catalytic oxidation of $S O_{2}$ to $S O_{3}$ .

$S O_{3}$ is absorbed in concentrated sulphuric acid.

$S O_{3}$ is directly absorbed in water.

Both the statements, $V_{2} O_{5}$ is used for catalytic oxidation of $S O_{2}$ to $S O_{3}$ and $S O_{3}$ is absorbed in concentrated sulphuric acid are correct.
