(D) On the industrial scale,hydrogen is prepared from water gas using the water-gas shift reaction:$CO + H_2O(g) \xrightarrow{	ext{catalyst}} CO_2 +

Vedclass · Accepted Answer

$CO$ is oxidised to $CO_2$ with steam in the presence of a catalyst followed by absorption of $CO_2$ in alkali

Vedclass · Answer

(D) On the industrial scale,hydrogen is prepared from water gas using the water-gas shift reaction:$CO + H_2O(g) \xrightarrow{	ext{catalyst}} CO_2 + H_2$The resulting $CO_2$ is removed by scrubbing the mixture with an alkali solution (e.g.,$NaOH$ or $K_2CO_3$):$CO_2 + 2NaOH \longrightarrow Na_2CO_3 + H_2O$Thus,$CO$ is oxidized to $CO_2$ using steam in the presence of a catalyst,and the $CO_2$ is subsequently removed by absorption in an alkali.
