A) The concentration of Cl₂ would increase as the reaction returned to equilibrium.
B) The concentration of both Cl₂ and F₂ would increase as the reaction returned to equilibrium.
C) The concentration of Cl₂ would decrease as the reaction returned to equilibrium.
D) The concentration of both Cl₂ and F₂ would decrease as the reaction returned to equilibrium.
E) The concentration of both F₂ and Cl₂ would remain the same because the reaction would be at equilibrium.
