Reaction Quotient

• The rate of the reaction.

• The equilibrium constant at a given temperature.

• The relative amounts of products and reactants at a specific time.

• The total energy change of the reaction.

If the reaction quotient Q has a smaller value than the related equilibrium constant, K, _________

• the reaction is at equilibrium

• the reaction is not at equilibrium, and will make more products at the expense of the reactants

• the reaction is not at equilibrium, and will make more reactants at the expense of the products

• the value of K will not increase until it is equal to Q

What happens to the amount of chemical reactants (measured in Molarity or pressure) as a chemical change progresses "to the right" towards products, aka: "in the forward direction?"

• it stays constant before it reaches equilibrium

• it goes up before it reaches equilibrium

• it decreases before it reaches equilibrium
