Answer 1

Answer: (B)

Sol. $ 2 SO _2( g )+ O _2( g ) \xrightarrow{ V _2 O _5} 2 SO _3( g )$ :
contact process
$4 NH _3( g )+5 O _2( g ) \xrightarrow { Pt ( s )- Rh ( s )} 4 NO ( g )+6 H _2 O ( g ) \text { : }$
Ostwald's process
$N _2( g )+3 H _2( g ) \xrightarrow{ Fe ( s )} 2 NH _3( g ) ; $ Haber's process
Vegetable oil $(l)+ H _2( g ) \xrightarrow{ Ni ( s )}$ vegetable ghee
Hydrogenation
