Which of the following statements about chemical equilibrium are not

true?

A The equilibrium constant is dependent on temperature.

B The equilibrium constant is independent of the concentrations of

reactants or products at certain reaction conditions.

C The initial concentrations of reactants and products will affect the

equilibrium position.

D When starting with only reactants, only the forward reaction will take

place until equilibrium is reached.

E When starting with only the products, the reverse reaction rate will exceed

the forward reaction rate until equilibrium is reached.

B. The equilibrium constant is independent of the concentrations of

reactants or products at certain reaction conditions.

D. When starting with only reactants, only the forward reaction will take

place until equilibrium is reached.

Explanation:

Hello,

For the B. option, remember that law of mass action states that the equilibrium constant always depends on the concentration or at least one variable defining the amount of substance.

For the D option, remember that the particles are in constant motion so there is going to be a progressive increasing in the product's concentration which also will promote the reverse reaction until equilibrium is reached.

Best regards.
