Methanol is manufactured from carbon (IV) oxide and hydrogen gas according to the equation.
Q69620191016.png
The reaction is carried out in the presence of a chromium catalyst at 400ºC and 30Kpa under these conditions, an equilibrium is reached when 2% of the carbon (IV) oxide is converted to methanol.

(i) Explain how the yield of methanol would be affected if; the manufacturing process above is carried out at, 200ºC and a pressure of 30Kpa.

(ii) Using a more efficient catalyst.

(i) The yield increased the equilibrium will shift from left to the right // forward reaction is
favoured.

(ii) The yield remain the same catalyst only change the rate of attainment of equilibrium // a catalyst has no effect on the position of the equilibrium.
