Chem

When a reaction mixture reaches chemical equilibrium, ____.

the rates of the forward and reverse reactions are equal

The equilibrium constant, K, relates quantity of products to reactants at a point when the reaction is ____.

At equilibrium

When you see coefficients, and you need to do Kc, or Kp, what do you do?

Square coefficients, then multiply the two concentrations

According to Le Chatelier's principle, when you remove a component from an equilibrium mixture, the reaction proceeds in the direction that favors ___.

production of the removed component

• When a reaction is at equilibrium, decreasing the concentration of one species in the system changes the reaction quotient and disrupts equilibrium. Since the reaction quotient is no longer equal to the equilibrium constant, the reaction shifts toward production of the removed component. The reaction will proceed in this direction until the reaction quotient and equilibrium constant are equal again and equilibrium is reestablished.

Which statement concerning the concentration of products and reactants at equilibrium is true?

The concentrations of the products and reactants do not change.

• Chemical equilibrium results when rates of the forward and reverse reactions are equal. Because products and reactants are being formed at the same rate, the concentrations of products and reactants do not change once equilibrium is established.

When doing Kc, or Kp, if there is a reactants or Product classified as a solid, or liquid do you apply the formula?

No, you can only find the values of Kc or Kp with (g) or (sq), if there is one of those values in it, you substitute it for a 1.
