What is $X$ in the following reaction?
$\mathrm{CO}+2 \mathrm{H}_2 \xrightarrow{x} \mathrm{CH}_3 \mathrm{OH}$
- A$623 \mathrm{~K} / 300 \mathrm{~atm}$
- B$\mathrm{KMnO}_4 / \mathrm{H}^{\oplus}$
- C$\mathrm{Zn} / \Delta$
- Correct answerD$\mathrm{ZnO}-\mathrm{Cr}_2 \mathrm{O}_3, 200-300 \mathrm{~atm}, 573-673 \mathrm{~K}$
Solution
The given reaction is for the industrial preparation methanol from a mixture of carbon monoxide and hydrogen . In the reaction the gaseous mixture is subjected to 200 atmosphere and then passed over heated catalyst mixture of ZnO and $\mathrm{Cr}_2 \mathrm{O}_3$ kept at $573-673 \mathrm{~K}$. This reaction results the formation of methanol vopours which are then condensed to liquid state.
Hence, the correct answer is option: 'D'.
