Briefly describe how to find the values for both enthalpy and entropy of dissolutionfrom the linear equation (1 paragraph or less)

The Gibbs energy of a pure substance is identical to another thermodynamic quantity: the chemical potential, . How does the chemical potential of liquid water relate to the chemical potential of solid ice at standard pressure (1 bar)? How does this change at high pressure? Does the rate at which the wire moves through the ice depend on the amount of weight placed on the wire? If so, how? Consider whether or not this is an equilibrium process. Does it matter how thick the wire is? If so, why? Does it matter if the wire can conduct heat? If so, why?

Two ideal gases under same pressure and temperature are allowed to mix in an isolated system – what will be sign of entropy change?

For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour. System A mixture of xenon (Xe) gas and hydrogen (H₂) gas at 2 atm and 48°C. 300 mL of a solution made from ammonium iodide (NH4I) dissolved in water. A solution made of ammonium iodide (NH I) in water, at 58°C. Change An additional 2.0 L of pure H₂ gas is added to the mixture, with the pressure kept constant at 2 atm. 0.5 g of NH I crystallizes out of the solution, without changing the temperature. 50. mL of pure water is added to the solution.

15. When a solute is able to go spontaneously into solution: (A) both the enthalpy (AHsoln) and the entropy (ASsoln) of mixing are always positive. (B) both the enthalpy (AHsoln) and the entropy (ASsoln) of mixing are always negative. (C) the enthalpy (AHsoln) is always negative, while the entropy (Scoln) is always positive. (D) the enthalpy (AHsoln) may be positive or negative, but the entropy (ASsoln) is always positive. (E) the enthalpy (AHsoln) is always negative, but the entropy (ASsoln) may be positive or negative.

When NaCl dissolves the temperature decreases and AG is negative. For the system, AHsys is positive and AS sys is also positive. This means that for the surroundings AHsurr is negative and ASsurr is also negative. Explain why NaCl dissolves even though it requires a net input of energy into the system.

Why do most polymer blends exhibit lower critical solution temperatures, rather than upper critical solution temperature?   Please describe in relation to entropy and Gibbs free energy. and also i want to know why polymer blends have the behavior of LCST ( compare with UCST )
