In context with the industrial preparation of hydrogen from water gas

1.	In context with the industrial preparation of hydrogen from water gas `(CO+H_(2))` , which of the following is the correct statement ?A. `CO` is oxidised to `CO_(2)` with steam in the presence of a catalyst followed by absorption of `CO_(2)` in alkaliB. `CO` and `H_(2)` are fractionally separated using difference in theire densitiesC. `CO` is removed by absorption in aqueous `Cu_(2)Cl_(2)`D. `CO` is removed by absorption in aqueous `Cu_(2)CL_(2)`
Answer» Correct Answer - a The water gas is mixed with excess of steam and passed `45^(@)C` over a heated catalyst `(Fe_(2)O_(3)+Cr_(2)O_(3)).CO` is mostly oxidised to `CO_(2)` and more `H_(2)` is set free. `CO_(2)` is absorbed in alkali. `underset("Water gas")(ubrace(CO+H_(2))) + underset("Steam")(H_(2)O) overset("Catalyst")(to) CO_(2) + 2H_(2)`
