55. Solving a chemistry problem

16. Calculate and plot the dependence of the electrostatic repulsion energy of two plane-parallel plates on the concentration of NaCl in an aqueous solution, varying from 1 to 10 mmol/l. When calculating, take the distance between the plates 20 nm; diffuse layer potential  = 310–2 V; temperature 298 K, dielectric constant of the medium 78.2.
