Question: Suppose the interaction between two atoms by the Lennard-Jones potential: ULJ= -A where the values of A and B are known to be A

Suppose the interaction between two atoms by the Lennard-Jones potential: ULJ= -A

Suppose the interaction between two atoms by the Lennard-Jones potential: ULJ= -A where the values of A and B are known to be A = 10-77 J.m6 and B = 10-134 J.m 1. What does the Lennard-Jones potential predict for the separation r = req when the energy is at the minimum (equilibrium) value, Umin. What is the umin fot this interaction at T=298 K? 2. What is the ratio of Umin to the purely attractive van der Waals component of the interaction potential at Teq. 3. What is the ratio of rea to ro defined by u(ro) = 0. 4. What is the ratio of rs to ro, where rs is the separation where the magnitude of the (attractive adhesion) force is maximum, Fmax. What is the value for Fmax between the two atoms?
