equilibrium ... again

CO(g) + 2H2 (two way arrow) CH3OH(g)
a)in industry the reaction is usually carried out at 300 atmospheres pressure. Explain the use of high pressure
b)Is the reaction which produces methanol exothermic or endothermic? Explain

a) With high pressure the equilibrium will move towards the side with less gas volumes. On the right you have 3 volumes(1 CO and 2H2) whereas on the left there is only one. So it will move towards methanol. Its more economic to do this in industry.
b) I think you're missing some info, does it tell you what the enthalpy value is for either the forward or the reverse reation?

Hess's cycle, if you're supposed to work it out.
