Question

question 6
if q = k
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:

1. For the first question, when $Q = K$, the reaction is at equilibrium. When $Q K$, the reaction goes backward.
2. For the second question, the equilibrium constant $K$ is calculated using concentrations at equilibrium, while the reaction - quotient $Q$ is calculated using concentrations at any point during the reaction.

Answer:

1. The reaction is at equilibrium
2. K is based on concentrations at equilibrium, while Q is based on concentrations at any point in the reaction
