Calculate and construct a potential energy interaction curve for spherical particles of radius r = 15 nm in an aqueous KCl solution with a concentration of c = 1.8 mmol / L using the following data: Hamaker constant A ^ * = 1.5 ∙ 10 ^ (- 20) J, the potential of the diffuse layer is φ_ = 20 mV, the temperature is 20 ° C, the relative dielectric constant of the medium is 80.1. The values of the energy of interaction of particles to determine at distances between surfaces h: 1, 2, 4, 8, 16, 32 nm.
