108. Solving a chemistry problem

Calculate and plot the potential energy curve of interaction of spherical particles with a radius of r=50 nm in an aqueous solution of KCl with a concentration of c=0.5 mmol/l according to the following data: Hamaker constant A* = 1.5×10–20 J, diffuse layer potential φd= 40 mV, temperature 20 °C, relative permittivity of the medium 80.1. The values of the particle interaction energy are determined at distances between the surfaces h: 1, 2, 4, 8, 16, 32 nm.
