42. Solving a chemistry problem

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