131.Solving a chemistry problem

22. Calculate and construct a potential interaction curve of spherical particles with a diameter of 40 nm in aqueous NaCl solution according to the following data: potential φ = 0,05 B; The Hamaker constant A = 0.1⋅10 -18 J; the parameter χ = 6 · 10 8 m -1; T = 293 K; ε = 81; ε 0 = 8.85⋅10 -12 F / m. The values of the total interaction energy can be calculated between the surfaces h = 3, 6, 12, 24, 48 nm.
