55. Calculate and plot the potential energy curve of interaction of spherical particles with radius r in an aqueous solution of KCl with concentration c according to the following data: Hamaker constant A * = 1.5 * 10-20 J, diffuse layer potential φδ (in the table), 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.
Problem Particle radius, nm φδ, mV s, mmol/l
