At equilibrium, is the sum of the concentrations of all of the reactants always equal to the sum of the concentrations of all of the products?

a. Yes. Equilibrium means the product of the concentrations of reactants and products are equal

b. No. Equilibrium has nothing to do with concentrations of reactants and products

c. Yes. At equilibrium K = 1, therefore [products] = [reactants]

d. No. At equilibrium the product of the concentrations of products and reactants are virtually never equal

2 What can accurately be said about equilibrium? Select all that apply to all equilibrium situations.

a.The rate of the forward reaction exceeds that of the reverse reaction.

b.It is microscopically dynamic, but macroscopically static.

c.The rates of the forward and reverse reaction are equal.

d.It is macroscopically dynamic, but microscopically static.

e. The rate of the reverse reaction is essentially 0.

f. The concentrations of the reactants and products are constant over time.

g. The concentration of the reactants and products are equal to one another.

hThe rate of the forward reaction is essentially zero.
