pls solve soon :)

the interaction between two isolated molecules of a gas can be described by the QA RTTA (15 MarkS) Lennard Jones potential energy function, given below. (r)=4[(r)12(r)6] (a) If the Lennard-Jones parameter b0 is 0.1m3/kmol, find the molecular diameter (b) Find the separation distance at when the potential energy is zero. (3 Marks) (c) The net force between two isolated molecules of a gas is 1.8791012N when the separation distance is twice the molecular diameter. Find the absolute value of the minimum potential energy (). ( 6 Marks) (d) Find the force between the molecules when the separation distance is half the molecular diameter. ( 3 Marks)
