Q11 / 180 · KCET 2017 · Chemistry
In the manufacture of hydrogen from water gas \( \left(\mathrm{CO}+\mathrm{H}_{2}\right) \), which of the following is correct
statement?
statement?
- Correct answerA\( \mathrm{CO} \) is oxidized to \( \mathrm{CO}_{2} \) with steam in the presence of a catalyst followed by absorption of
\( \mathrm{CO}_{2} \) in alkali. - B\( \mathrm{CO} \) and \( \mathrm{H}_{2} \) are separated based on difference in their densities.
- CHydrogen is isolated by diffusion.
- D\( \mathrm{H}_{2} \) is removed by occlusion with pd.
Solution
In the manufacture of hydrogen from water gas \( \left(\mathrm{CO}+\mathrm{H}_{2}\right) \)
\( \mathrm{CO}+\mathrm{H}_{2}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{CO}_{2}+2 \mathrm{H}_{2} \)
\( \mathrm{CO} \) is oxidized to \( \mathrm{CO}_{2} \) with steam in the presence of a catalyst followed by absorption of \( \mathrm{CO}_{2} \) in alkali.
\( 3 \mathrm{CO}_{2}+4 \mathrm{~N} a \rightarrow 2 \mathrm{Na}_{2} \mathrm{CO}_{3} \)
\( \mathrm{CO}+\mathrm{H}_{2}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{CO}_{2}+2 \mathrm{H}_{2} \)
\( \mathrm{CO} \) is oxidized to \( \mathrm{CO}_{2} \) with steam in the presence of a catalyst followed by absorption of \( \mathrm{CO}_{2} \) in alkali.
\( 3 \mathrm{CO}_{2}+4 \mathrm{~N} a \rightarrow 2 \mathrm{Na}_{2} \mathrm{CO}_{3} \)
Hence, the correct answer is option: 'A'.
