Which of the following equilibria will shift towards the formation of more products if the reaction at equilibrium is compressed into half its volume? 1. 2N2O(g) = 2N2(g) + O2(g) II. 2CO(g) + O2(g) = 2CO2(g) III. N2(g) + O2(g) = 2NO(g) Both II and III. All three reactions will shift towards the formation of more products.
