139. Solving a chemistry problem

Calculate and plot potential curves of pair interaction of spherical particles in an aqueous solution of a monovalent electrolyte at a temperature of 293 K. The interaction energies should be calculated for the distances between particles 2,3,4,5,7,10,15,20,30,40 and 50 nm. Analyze the effect of particle size on the shape of potential interaction curves
