The reaction system  is at equilibrium. Which of the following statements describes the behavior of the system if POCl is added to the container?

Quizplus · Accepted Answer

Since the reaction system is already at equilibrium, the addition of POCl will disrupt the equilibrium, causing the system to shift to re-establish equilibrium. The addition of more reactants (POCl) will favor the reverse reaction, resulting in the production of more reactants (PCl3 and Cl2) and less product (POCl3). Therefore, the reverse reaction will proceed to establish equilibrium. The partial pressures of POCl₃ and POCl will change as the system shifts, but the partial pressure of chlorine will remain steady since it is a product of the reaction.
