- A \(623 \mathrm{~K} / 300 \mathrm{~atm}\)
- B \(\mathrm{KMnO}_4 / \mathrm{H}^{\oplus}\)
- C \(\mathrm{Zn} / \Delta\)
- D \(\mathrm{ZnO}-\mathrm{Cr}_2 \mathrm{O}_3, 200-300 \mathrm{~atm}, 573-673 \mathrm{~K}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{ZnO}-\mathrm{Cr}_2 \mathrm{O}_3, 200-300 \mathrm{~atm}, 573-673 \mathrm{~K}\)
Step-by-step Solution
Detailed explanation
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 \(\mathrm{ZnO}\) and \(\mathrm{Cr}_2 \mathrm{O}_3\)…
