Calculate the equilibrium pressure of gas at 773 K. PbCO 3 (s) rightleftharpoons PbO(s)+CO 2 (g); triangle H^ 0 =+88.3 kJ; triangle S^ 0 (J/K) 68.7

Two liquids A and B mix to form an ideal solution. Consider A to be the solvent (majority component) and B to be the solute (minority component). What is the relationship between the Gibbs energy and chemical potential for a pure phase? How does the Gibbs energy of A(solution) COmpare to Gibbs energy of Apure liquid)? How does the Gibbs energy of B(solution) compare to Gibbs energy of B(pure liquid)? d. When B is added to pure A, what happens to the Gibbs energy of A? а. b. C. e. Why does the Gibbs energy of the solvent of an ideal solution (in this case, A) decrease upon the addition of a solute (in this case, B)? Provide mathematical and conceptual explanations.
