Manufacturing of Sulphuric Acid by Contact Process

Which of the following is formed when ${\mathrm{SO}}_3$ is absorbed by concentrated ${\mathrm{H}}_2{\mathrm{SO}}_4$

Industrially sulphuric acid is manufactured by-

What is the purpose of Contact Process?

The following question consists of two statements one labelled ASSERTION $\left(\mathrm{A}\right)$ and the another labelled REASON $\left(\mathrm{R}\right)$. Select the correct answer to the question from the codes given below:

Assertion: In contact process of the manufacture of ${\mathrm{H}}_2{\mathrm{SO}}_4$, conversion of ${\mathrm{SO}}_2$ to ${\mathrm{SO}}_3$ by the reaction with oxygen, takes place in the presence of a catalyst ${\mathrm{V}}_2{\mathrm{O}}_5$.

Reason: The reaction which involves the conversion of ${\mathrm{SO}}_2$ to ${\mathrm{SO}}_3$, is exothermic, reversible, and the forward reaction leads to a decrease in volume.

The following catalyst is used in the manufacturing of sulphuric acid by lead chamber process.

Bleaching action of sulphur dioxide (${\mathrm{SO}}_2$) is because of:

For preparing very pure sulphuric acid on large scale, the raw materials are _____.

The process used to industrially prepare sulphuric acid is _____.

Match List I (substances) with List II (processes) employed in the manufacture of the substances and select correct option:


 

The key step in the manufacturing of ${\mathrm{H}}_2{\mathrm{SO}}_4$ by contact process is:

What is true about ${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_7$?
