Carbon monoxide reacts with hydrogen under certain conditions to form methanol (CH3OH). Write a balanced chemical equation for this reaction indicating the physical state of reactants and products as well as the conditions under which this reaction takes place.


Carbon monoxide reacts with hydrogen under certain conditions to form methanol (CH3OH).

The balanced equation is given by :

$CO( g) \ +\ 2H_{2}( g) \ \xrightarrow[ZnO\ +\ CrO_{3}]{300\ atm,\ 300\ C} \ CH_{3} OH( l)$

The conditions for this reaction to take place are:

  •  pressure of 300 atmospheres (written as 300 atm),
  •  temperature of 300oC, 
  •  catalyst which is a mixture of zinc oxide and chromium oxide (ZnO + CrO3).
