What is X in the following reaction? CO+2 H_2 x CH_3 OH

What is

X

in the following reaction?

\mathrm{CO}+2 \mathrm{H}_2 \xrightarrow{x} \mathrm{CH}_3 \mathrm{OH}

Options

A $623 \mathrm{~K} / 300 \mathrm{~atm}$
B $\mathrm{KMnO}_4 / \mathrm{H}^{\oplus}$
C $\mathrm{Zn} / \Delta$
D $\mathrm{ZnO}-\mathrm{Cr}_2 \mathrm{O}_3, 200-300 \mathrm{~atm}, 573-673 \mathrm{~K}$

Correct answer

D. $\mathrm{ZnO}-\mathrm{Cr}_2 \mathrm{O}_3, 200-300 \mathrm{~atm}, 573-673 \mathrm{~K}$

Step-by-step 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.
