What is X in the following reaction? CO +2 H ₂ x CH ₃ OH

Options

  1. A623 ~K / 300 ~atm
  2. BKMnO ₄ / H ^
  3. CZn /
  4. DZnO - 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 vopours which are then condensed to liquid state.
