- for C2H2 1- Calculate the separation at which the minimum of the potential energy occur.2- verify that at this minimum the potential energy V = ─ .3- Choose values of r such that all characteristic points and areas are shown clearly on the graph. Let the x-axis be r in pmGive the effect on point (x,y,x) on each operation:The cohesive energy density, U, is defined as U/V, where U is the mean potential energy of attraction within the sample and V its volume. Show that U = 1/2N2∫V(R)dτ where N is the number density of the molecules and V(R) is their attractive potential energy and where the integration ranges from d to infinity and over all angles. Go on to show that the cohesive energy density of a uniform distribution of molecules that interact by a van der Waals attraction of the form −C6/R6 is equal to −(2π/3)(NA2/d3M2)ρ2C6, where ρ is the mass density of the solid sample and M is the molar mass of the molecules.
