Question

which of the following statements describe the conditions of the \current\ system?

\\(q > k\\) and the reaction goes in reverse to use up products and generate more reactants.

\\(q < k\\) and the reaction goes in reverse to use up products and generate more reactants.

\\(q = k\\) and the system is at equilibrium.

\\(q < k\\) and the reaction proceeds forward to use up reactants and generate more products.

Explanation:

Compare Q and K

Using the Reaction Quotient and Chemical Equilibrium knowledge points

• When \(Q > K\), the concentration of products is higher than at equilibrium. To reach equilibrium, the system shifts in reverse (left) to consume products and produce more reactants.
• When \(Q < K\), the concentration of reactants is higher than at equilibrium. The system shifts forward (right) to consume reactants and produce more products.
• When \(Q = K\), the system is at equilibrium.

Identify the correct statement

Using the Reaction Quotient and Chemical Equilibrium knowledge points

• The option stating "\(Q > K\) and the reaction goes in reverse to use up products and generate more reactants" is scientifically correct.
• The option stating "\(Q < K\) and the reaction goes in reverse..." is incorrect because a system with \(Q < K\) shifts forward.
• The option stating "\(Q = K\) and the system is at equilibrium" is a correct general statement, but the selected option in the image (indicated by the radio button marker) is the first option: "\(Q > K\) and the reaction goes in reverse to use up products and generate more reactants".

Answer:

• (A) Q &gt; K and the reaction goes in reverse to use up products and generate more reactants (Correct answer)
• (B) Q &lt; K and the reaction goes in reverse to use up products and generate more reactants
• (C) Q = K and the system is at equilibrium.
• (D) Q &lt; K and the reaction proceeds forward to use up reactants and generate more products
