Multiple Choice

Which of the following statements regarding the law of mass action and the mass action expression is NOT true?

• A)The law of mass action defines the equilibrium constant to be the ratio of the forward and reverse rate constants for a particular equilibrium expression.
• B)The law of mass action states that the ratio of product concentrations to reactant concentrations,raised to powers equal to their coefficients in a balanced chemical reaction,has a characteristic value at a given temperature.
• C)The mass action expression is equivalent to the equilibrium expression in form but may be applied to reaction mixtures that are not at equilibrium.
• D)At a given temperature,the characteristic ratio of products to reactants at equilibrium will be the same regardless of the composition of the starting mixture.
• E)At a given temperature,the equilibrium concentrations of products and reactants depend on the composition of the starting mixture.
