Methanol is manufactured from carbon (IV) oxide and hydrogen gas according to the
equation below:
The reaction is carried out in the presence of a chromium catalyst at 700K and 30kPa. Under
these conditions, an equilibrium is reached when 2 % of the carbon (iv) oxide is converted to
methanol?
(a) How does the rate of forward reaction compare with that of the reverse reaction
when 2% of the carbon(iv)oxide is converted to methanol?
(b) Explain how each of the following conditions would affect the yield of methanol:
(i) Reduction in pressure
(ii) Using a more efficient catalyst.
(c) If the reaction is carried out at 500K and 30kPa the percentage of carbon (iv) oxide
converted is higher than 2%. What is the sign of ΔH for the reaction? Explain.
