38. Solving a chemistry problem

28(7). Calculate and plot the potential curves of pairwise interaction of spherical particles in an aqueous solution of a monovalent electrolyte at a temperature of 293 K. The values of particle radii r, electrolyte concentration c0, diffuse layer potential φ, and Hamaker constant A for various dispersed systems are given in the table below. Interaction energies should be calculated for distances between particles of 2,3,4,5,7,10,15,20,30,40 and 50 nm. Analyze the influence of particle sizes on the shape of potential interaction curves
