Solution

The correct option is D $C O (g) + H_{2} O (g) C a t a l y s t - ---- \to 673 K C O (g) + H_{2} (g)$
The gaseous mixture of carbon monoxide and hydrogen from these reactions (called synthesis gas) is used in the preparation of methanol. Hydrogen is obtained from this mixture free of carbon monoxide by means of the water-gas shift reaction, an industrial process in which carbon monoxide reacts with steam in the presence of a catalyst producing carbon dioxide and hydrogen:
$C O + H_{2} O \to C O_{2} + H_{2}$
