Home » When a mixture of gases X and Y is compressed to 300 atm pressure and then passed over a catalyst consisting of a mixture of zinc oxide and chromium oxide (heated to a temperature of 300oC), then an organic compound Z having the molecular formula CH4O is formed. X is a highly poisonous gas which is formed in appreciable amounts when a fuel burns in a limited supply of air; Y is a gas which can be made by the action of a dilute acid on an active metal; and Z is a liquid organic compound which can react with sodium metal to produce hydrogen gas. (a) What are X, Y and Z? (b) Write a balance chemical equation of the reaction which takes place when X and Y combine to form Z. Indicate the conditions under which the reaction occurs.

(a) X= Carbon monoxide gas (CO); Y= Hydrogen gas (H2); Z = Methanol (CH3OH or CH4O)

(b)CO(g) + 2H2(g) → CH3OH (l)

Carbon monoxide when reacts with hydrogen gas under a pressure of 300atmosphere and a temperature of 300℃ and a catalyst which is a mixture of Zinc oxide and chromium oxide
