Unformatted text preview: O C. S FeCl 3 > S FeCl 3 *3H 2 O and H FeCl 3 < H FeCl 3 *3H 2 O D. S FeCl 3 < S FeCl 3 *3H 2 O and H FeCl 3 < H FeCl 3 *3H 2 O For a non-ionic solid, what determines the sign of H when the solid dissolves in water? You experimentally determine that, at equilibrium, the reaction of hydrogen and fluorine to make hydrofluoric acid has P H2 = 10-30 atm, P F2 = 10-10 atm, and P HF = 1 atm. If another system starts with P H2 = 100 atm, P F2 = 10-18 atm, and P HF = 10-18 atm , will the pressure of HF increase, decrease, or remain unchanged? Justify your answer by determining the sign of G for this system. A particularly liquid can exist in both cis and trans isomers. Write a valid thermodynamic equilibrium constant for this liquid. 1...
