Formation of $SO_3$ in the contact process

Vedclass · Answer

(B) In homogeneous catalysis,the reactants and the catalyst are in the same phase (usually liquid or gas). In the contact process,$SO_2$ (gas) and $O_2$ (gas) react in the presence of $V_2O_5$ (solid) to form $SO_3$ (gas). This is an example of heterogeneous catalysis. In the chamber process,$NO$ (gas) acts as a catalyst for the oxidation of $SO_2$ (gas) to $SO_3$ (gas),which is homogeneous. Hydrolysis of sugar in the presence of acid is homogeneous. Decomposition of $KClO_3$ (solid) in the presence of $MnO_2$ (solid) is heterogeneous,but the question asks for the best fit among the options provided. The contact process is the classic textbook example of heterogeneous catalysis.

Column-$I$	Column-$II$
$A. V_2O_5$	$i. \text{Conversion of } SO_2 \text{ to } SO_3$
$B. Ni$	$ii. \text{Hydrogenation of oils}$
$C. MnO_2$	$iii. \text{Preparation of } O_2 \text{ from } KClO_3$
$D. Fe$	$iv. \text{Haber's process}$
