54. Solving a chemistry problem

4. Calculate the total energy U = Ue Um of the interaction of two plane-parallel plates at a distance of 5, 10, 20, 30 and 50 nm in an aqueous solution of a monovalent electrolyte at a diffusion layer potential φδ = 0.02 V. Using the following data: A* = 5 • 10-20 J, c0 = 10-4 mol / l, T = 273 K, ε = 87.8 build a potential curve of the interaction of plates between surfaces.
