True or false? (a) In an ideal solution, there are no intermolecular interactions.

(b) Δmix G (at constant Tand P) must be negative when a solution is formed from two pure liquids.

(c)Δmix S(at constant Tand P) must be negative when a solution is formed from two pure liquids.

(d) At pressures below the pressure of the solid–liquid–vapor triple-point pressure of a pure substance, a stable liquid cannot exist.

(e) The solid–vapor equilibrium line on the P-versus-Tphase diagram of a pure substance starts at the origin (P= 0, T= 0). (e) If liquids B and C form an ideal solution and if   at temperature T, then the vapor in equilibrium with a liquid solution of B and C at Tmust have the same composition as the liquid solution.
