142. Solving a chemistry problem

9.20. Calculate the e´-potential, taking into account the surface conductivity at the interface of the quartz diaphragm, a solution of potassium chloride and plot the concentration dependence of C
electrolyte according to the following data:
C * 10–3, mol / m3 0.1 0.2 0.45 0.7 1.0
Xv * 102, Ohm – 1 * m – 1 2 2.5 2.8 3 3.5
v 109, m3 / s 1.5 1.0 0.5 0.25 0.1
e is 81; n = 1 * 10-3 Pa * s; a = 3.0; I = 1.5 * 10-3 A.
