NEET levelSingle correct optionDifficulty 1 of 3df011

Finely divided nickel is used industrially as a catalyst for

Asynthesis of ammonia from $N X_{2}$ and $H X_{2}$
Bhydrogenation of vegetable oils to fats
Coxidation of $NH X_{3}$ to NO
Doxidation of $SO X_{2}$ to $SO X_{3}$

Answer: B

Ni adsorbs

H X_{2}

and adds it across C=C bonds of unsaturated oils. Ammonia oxidation uses Pt-Rh,

SO X_{2}

oxidation uses

V X_{2} O X_{5}

and the Haber process uses Fe.
