BITSAT Chemistry Question (2024) — Solution
Options
- A. 623 ~K / 300 ~atm
- B. KMnO _4 / H ^
- C. Zn /
- D. ZnO - Cr _2 O _3, 200-300 ~atm , 573-673 ~K
Answer
D. ZnO - Cr _2 O _3, 200-300 ~atm , 573-673 ~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 Cr _2 O _3 kept at 573-673 ~K . This reaction results the formation of methanol vopours which are then condensed to liquid state.
