Consider this reaction at equilibrium: CO(g) + Cl2(g) ⇌ COCl2(g) Predict whether the reaction will shift left, shift right, or remain unchanged after each disturbance. a. COCl2 is added to the reaction mixture. b. Cl2 is added to the reaction mixture. c. COCl2 is removed from the reaction mixture.

검증된 단계별 안내

Identify the principle that governs the shift in equilibrium: Le Chatelier's Principle, which states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.
For part (a), when COCl2 is added, the system will try to reduce the concentration of COCl2 by shifting the equilibrium to the left, favoring the formation of CO and Cl2.
For part (b), when Cl2 is added, the system will try to reduce the concentration of Cl2 by shifting the equilibrium to the right, favoring the formation of COCl2.
For part (c), when COCl2 is removed, the system will try to increase the concentration of COCl2 by shifting the equilibrium to the right, favoring the formation of COCl2 from CO and Cl2.
Summarize the shifts: (a) shift left, (b) shift right, (c) shift right.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Le Chatelier's Principle

Le Chatelier's Principle states that if a dynamic equilibrium is disturbed by changing the conditions, the system will adjust to counteract the change and restore a new equilibrium. This principle helps predict the direction of the shift in a reaction when a change in concentration, pressure, or temperature occurs.

Le Chatelier's Principle

Equilibrium Constant (K)

The equilibrium constant (K) quantifies the ratio of the concentrations of products to reactants at equilibrium for a given reaction at a specific temperature. Changes in concentration of reactants or products can affect the position of equilibrium, but the value of K remains constant unless the temperature changes.

Concentration Changes

Changes in the concentration of reactants or products can shift the position of equilibrium. Adding a reactant or product will shift the equilibrium towards the side that consumes the added substance, while removing a substance will shift it towards the side that produces more of that substance, thereby helping to re-establish equilibrium.

Consider the reaction: A(g) ⇌ B(g) + C(g) Find the equilibrium concentrations of A, B, and C for each value of Kc. Assume that the initial concentration of A in each case is 1.0 M and that the reaction mixture initially contains no products. Make any appropriate simplifying assumptions. b. Kc = 0.010
