Consider the following exothermic reaction (with an enthalpy change of -514kJ) at equilibrium:

2 CO2 (g) <-----> 2 CO (g) + O2 (g)

Le Chatelier's principle states that the equilibrium partial pressure of CO(g) can be maximized by carrying out the reaction .

(a) at high temperature and high pressure

(b) at high temperature and low pressure

(c) at low temperature and low pressure

(d) at low temperature and high pressure

(e) none of the choices given here
