The statements in the following multiple choices deal with the concepts of reaction quotients and equilibrium. Choose the statement which is true.
a) As a reaction approaches equilibrium its Q value rises and its K value falls until they are equal.
b) If Q < K the reaction must progress backwards to attain equilibrium.
c) As a reaction approaches equilibrium its Q value falls and its K value rises until they are equal.
d) A reaction quotient equals the equilibrium constant at equilibrium.
e) As a reaction progresses backwards toward equilibrium K is the highest value Q attains.
