According to Le Chatelier's principle, a system at equilibrium will respond to any stress placed on the system by shifting the equilibrium position to counteract the stress. In this case, the reaction is exothermic, so decreasing the temperature will favor the forward reaction to produce more heat. Increasing pressure will favor the side with fewer moles of gas, which in this case is the product side, so high pressure will also favor the forward reaction. Therefore, the conditions that favor maximum conversion of reactants to products are high pressure and low temperature.

For the Reaction CO(g)+ 3H2(g)⇌ CH4(g)+ H2O(g)q = −206 KJ

For the Reaction CO(g)+ 3H₂(g)⇌ CH₄(g)+ H₂O(g)q = −206 KJ
