Question

In the preparation of sulphuric acid, V2O5 is used in the reaction which is (A) S + O 2 arrow SO 2 (B) SO 2+ H 2 O arrow H 2 SO 4 (C) 2 SO 2+ O 2 arrow 2 SO 3 (D) None of these

Tardigrade Admin · Accepted Answer

In contact process of manufacture of H 2 SO 4 first of all SO 2 is oxidised to SO 3 by atmospheric oxygen in presence of V 2 O 5 as a catalyst. 2SO2 + O2 xrightarrowV2O5 2SO3

Q. In the preparation of sulphuric acid, $V_{2} O_{5}$ is used in the reaction which is

$S + O_{2} \to S O_{2}$

$S O_{2} + H_{2} O \to H_{2} S O_{4}$

$2 S O_{2} + O_{2} \to 2 S O_{3}$

None of these

In contact process of manufacture of $H_{2} S O_{4}$ first of all $S O_{2}$ is oxidised to $S O_{3}$ by atmospheric oxygen in presence of $V_{2} O_{5}$ as a catalyst.
$2 S O_{2} + O_{2} V_{2} O_{5} 2 S O_{3}$

Q. In the preparation of sulphuric acid, V2​O5​ is used in the reaction which is

S+O2​→SO2​

SO2​+H2​O→H2​SO4​

2SO2​+O2​→2SO3​
