1011. Solving a chemistry problem

41. Calculate the potential energy and interactions of two plane-parallel plates located in an aqueous electrolyte solution with concentration c, at the value of the diffuse layer potential φδ, relative dielectric constant εr and temperature t. When calculating, take the Hamaker constant A* = 3.0*10-20 J. Calculations are made for distances between the plates h: 2, 5, 10, 15, 25, 50 nm. Plot the dependence u=f(h).
