25. Solving a chemistry problem

28. Calculate and plot the potential interaction curve of spherical particles with a diameter of 200 nm in an aqueous solution of NaCl using the following data; potential φδ = 20 mV; Hamaker constant A* =0.5*10-19 J; parameter χ =1*10^8 m-1 and temperature 293 K. Determine the values of the total interaction energy at distances of I, 2, 5, 10, 20 and 40 nm.
