19Which of the following about thermodynamic equilibria is not true?
(A) At phase equilibrium, a substance that occurs in two phases will have the same concentration in both phases.
(B) For a single component substance at a fixed value of pressure, the change of slopes in the plot of the chemical potential versus temperature across different phases represents the variation of the molar entropies of phases.
(C)△_rG is the net difference of chemical potentials between products and reactants for the reaction.
(D) △_rGº representing the change in standard Gibbs energy for the reaction between unmixed reactants to form unmixed products is a function of temperature only.
(E)△_rG = −RT In K_p+ RT InQ where Q represents the reaction quotient.
