According to Le Chatelier's principle, when a system at chemical equilibrium is subjected to a change in temperature, pressure, or concentration of reactants or products, the system will respond in such a way as to counteract the change. In this case, the forward reaction (C(s) + CO2(g) + heat ⇌ 2CO(g)) is exothermic, meaning it releases heat. Therefore, increasing the temperature will shift the equilibrium towards the reactants (CO2 and C), decreasing the yield of CO. On the other hand, decreasing the pressure will also shift the equilibrium towards the reactants, as there are fewer gas molecules on the product side. Therefore, the best choice is high temperature and low pressure.
