What is (X ) in the following reaction? ( CO +2 H ₂ X CH ₃ OH )
Options
- A(623 ~K / 300 ~atm )
- B( KMnO ₄ / H ^ )
- C( Zn / )
- D( ZnO - Cr ₂ O ₃, 200-300 ~atm , 573-673 ~K )
Correct 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 vapours which are then condensed to liquid state. ( CO +2 H ₂ [ 200-300 ~atm , 573-673 ~K ] ZnO - Cr ₂ O ₃(X) CH ₃ OH )
