In context with the industrial preparation of hydrogen from water gas `(CO+H_(2))`. Which of the following is the correct statement?

Options

A. CO is removed by adsorption in aqueous `Cu_(2)Cl_(2)` Solution
B. `H_(2)` is removed through occusion with Pd
C. CO is oxidized to `CO_(2)` with steam in the presence of a catalyst followed by adsorption of `CO_(2)` in alkali
D. CO and `H_(2)` are fractionally separated using differences in their densities

Answer

C

Explanation

CO is oxidised to `CO_(2)` with steam in the presence of a catalyst followed by absorption of `CO_(2)` in alkali.
`CO+H_(2) underset("catalyst")overset("Steam")(rarr)CO_(2)+2H_(2) overset(KOH)(rarr)K_(2)CO_(3)`
