During a chemical reaction, if Q = K, what can be said about the reaction?
A. The reaction still proceeds in both directions, but the net result is that the reactant and product concentrations do not change.
B. The amount of product is always equal to the amount of reactant.
C. The reaction proceeds in the direction of the products.
D. No additional reaction occurs, since the system is at equilibrium.
A.
This is the definition of equilibrium.

To determine the answer to this question, we need to understand what Q and K represent in a chemical reaction.
Q represents the reaction quotient, which is a measure of the relative concentrations of the reactants and products at a particular point in the reaction.
K represents the equilibrium constant, which is a measure of the relative concentrations of the reactants and products when the reaction has reached equilibrium.
When Q = K, it means that the reaction quotient is equal to the equilibrium constant. This indicates that the reaction is at equilibrium, meaning the reaction has reached a state where the concentrations of reactants and products no longer change with time.
Therefore, the correct answer is D. No additional reaction occurs, since the system is at equilibrium.
