Consider the following reaction at equilibrium. what effect will removing no2 have on the system? so2(g) + no2(g) ↔ so3(g) + no(g) consider the following reaction at equilibrium. what effect will removing no2 have on the system? so2(g) + no2(g) so3(g) + no(g) the reaction will shift to decrease the pressure. the equilibrium constant will decrease. the reaction will shift in the direction of reactants. the reaction will shift in the direction of products. no change will occur since so3 is not included in the equilibrium expression.
