Consider this reaction at equilibrium: 2 BrNO(g) ⇌ 2 NO(g) + Br2(g) Predict whether the reaction will shift left, shift right, or remain unchanged after each disturbance. a. NO is added to the reaction mixture.

검증된 단계별 안내
1
Identify the reaction and the change applied: The reaction given is 2 BrNO(g) ⇌ 2 NO(g) + Br2(g), and the disturbance is the addition of NO(g) to the reaction mixture.
Recall Le Chatelier's Principle, which states that if a system at equilibrium is disturbed, it will adjust itself to counteract the disturbance and restore a new equilibrium.
Analyze the effect of adding NO(g): Adding more NO(g) increases the concentration of NO(g) on the right side of the equation.
Predict the shift due to the disturbance: According to Le Chatelier's Principle, increasing the concentration of a product (NO(g)) will shift the equilibrium to the left to reduce the concentration of NO(g) by converting it back to BrNO(g).
Conclude the direction of the shift: The reaction will shift to the left in response to the addition of NO(g).

주요 개념

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 equilibrium when a reactant or product concentration is altered.

Equilibrium Constant (K)

The equilibrium constant (K) is a numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a given reaction at a specific temperature. Changes in concentration, pressure, or temperature can affect the value of K, influencing the position of equilibrium.

Reaction Quotient (Q)

The reaction quotient (Q) is a measure of the relative concentrations of products and reactants at any point in time, not just at equilibrium. By comparing Q to K, one can determine the direction in which the reaction will shift to reach equilibrium: if Q < K, the reaction shifts right; if Q > K, it shifts left.
