Question

the mixture of carbon monoxide and hydrogen gas is compressed to 300 atmospheric pressure and then passed over a catalyst (mixture of zinc oxide and chromium oxide heated to a temperature of 300 degree Celsius to form methanol)​

Answer 1

is carbon monoxide gas (CO); Y is hydrogen gas H2; Z is methanol (or Methyl alcohol) (CH3OH)

Note: CH4O=CH3OH= methanol.

b) Formation of Z;

             CO(g)+2H2(g)300atm, 3000CZnO, CrO3CH3OH(l)

                                                                 Methanol (Methyl alcohol)

The conditions for this reaction to take place are: a pressure of 300 atmosphere (written as 300 atm), a temperature of 3000C , and a catalyst which is a mixture of zinc oxide and chromium oxide (ZnO+CrO3)
