Vedclass · Answer

(A) The reaction of carbon monoxide with hydrogen yields different products depending on the catalyst used:$1$. $CO + 3 H_2 \xrightarrow{Ni} CH_4 + H_2 O$ (Catalyst $A = Ni$)$2$. $CO + 2 H_2 \xrightarrow{ZnO-Cr_2 O_3} CH_3 OH$ (Catalyst $B = ZnO-Cr_2 O_3$)$3$. $O_2 + 2 H_2 \xrightarrow{Pt} 2 H_2 O$ (Catalyst $C = Pt$)Therefore,the catalysts $A, B, C$ are $Ni, ZnO-Cr_2 O_3, Pt$ respectively.

Consider the reactions:
$I$. $CO + 3 H_2 \xrightarrow{A} CH_4 + H_2 O$
$II$. $CO + 2 H_2 \xrightarrow{B} CH_3 OH$
$III$. $O_2 + 2 H_2 \xrightarrow{C} 2 H_2 O$
The catalysts $A, B, C$ are respectively:
