What is the catalyst used for oxidation of SO2 to SO3 in lead chamber process for manufacture of sulphuric acid?

Question

What is the catalyst used for oxidation of SO2 to SO3 in lead chamber process for manufacture of sulphuric acid? (A) Nitric oxide (B) Nitrous oxide (C) Potassium iodide (D) Dilute HCl

Tardigrade Admin · Accepted Answer

In lead chamber process, a mixture containing

S O_{2}

, air NO is treated with steam

(H_{2} O)

.

In this reaction, NO (nitric oxide) act as a catalyst.

2 S O_{2} + (From air) O_{2} + 2 H_{2} O + Catalyst [NO] \to 2 H_{2} S O_{4} + Catalyst [NO]

Q. What is the catalyst used for oxidation of SO2​ to SO3​ in lead chamber process for manufacture of sulphuric acid?

Nitric oxide

Nitrous oxide

Potassium iodide

Dilute HCl

In lead chamber process, a mixture containing SO2​, air NO is treated with steam (H2​O). In this reaction, NO (nitric oxide) act as a catalyst. 2SO2​+ (From air) O2​​+2H2​O+ Catalyst [NO]​→2H2​SO4​+ Catalyst [NO]​

Q. What is the catalyst used for oxidation of $S O_{2}$ to $S O_{3}$ in lead chamber process for manufacture of sulphuric acid?

In lead chamber process, a mixture containing $S O_{2}$ , air NO is treated with steam $(H_{2} O)$ .

In this reaction, NO (nitric oxide) act as a catalyst.

$2 S O_{2} + (From air) O_{2} + 2 H_{2} O + Catalyst [NO] \to 2 H_{2} S O_{4} + Catalyst [NO]$
