Question

question 6
if q=k, this means that
the reaction is at equilibrium.
the reaction will go forward.
the reaction will go backward.

question 7
what is the difference between q and k?
k is for gases, but q is for liquids and solids.
q is always greater than k.
there is no difference, q and k are always the same.
k is based on concentrations at equilibrium, while q is based on concentrations at any point in the reaction

Explanation:

Question 6

In chemical equilibrium, \( Q \) (reaction quotient) and \( K \) (equilibrium constant) are compared. When \( Q = K \), the ratio of product concentrations to reactant concentrations (each raised to their stoichiometric coefficients) is the same as at equilibrium. This means there is no net change in the concentrations of reactants and products, so the reaction is at equilibrium.

• \( K \) (equilibrium constant) is calculated using concentrations of reactants and products at equilibrium.
• \( Q \) (reaction quotient) is calculated using concentrations of reactants and products at any point during the reaction (not necessarily at equilibrium).

Answer:

the reaction is at equilibrium.
