Methanol (CH3OH) is manufactured by the reaction of carbon monoxide with hydrogen in the presence of a ZnO/Cr2O3 catalyst
CO(g) + 2H (g)?> CH3OH(g) change in H_o = -91 kJ
Does the amount of methanol increase, decrease, or remain the same when an equilibrium mixture of reactants and products is subjected to the following changes?
a) The temperature is decreased
b) The volume is increased
c) Helium is added
d) CO is added
e) The catalyst is removed
