Example text

D. 2 in the textbook) (BockrisGam boaAldeco) Answer: The ion-dipole interaction energy in the gas phase is given by (cf. Eq. , the charge in Coulombs, the distance in meters, and the free energy in joules per mol. 8 kJ mol-I The Born term is given in the mksa system by (cf. Eq. 7% larger than the Born term. 15 The interaction energy of the iodide ion with water dipoles in gas phase is -171 kJ mol -1 at 298 K. Calculate the radius of the water molecule. Take the iodide radius and the dipole moment of water from tables in Chapter 1.

See Fig. 3(b). (e) With the angle between H-O-H equal to 120°, a new set of variables (a', b' and c ') is assigned. 104) ION-SOLVENT INTERACTIONS 45 o o Ii Ii Ii (a) (b) (c) Fig. 3. 34. f = 1. 86D See Fig. 3(c). Comment This problem follows the 1933 Bernal and Fowler approach, which is still very appreciable. , quadrupole ones, have been proposed in latter years. 35 (a) Using data for the solution enthalpy (Allso/n ) and lattice enthalpy (AIl/alike = -Lsub) in the Table below, calculate the hydration heats for various alkali halides (AIls).

Besides, iJHsoln can be accurately measured. (b) In the solution process: MX (s ) ~ M + (aq) + X - (aq), the parameter that indicates whether or not the salt dissolves is L1Gsoln . The more negative L1Gsoln is, the more stable the ions are in solution. J{ soln - TAS soln . 4} and r being the radius of the ion.
