The mean separation between chlorine molecules, cl2, at a temperature of 298.15 k and a pressure of 1 bar is 3.5 nm. given the values of the lennard–jones parameters are latex: \epsilonϵ = 368 kj mol–1 and r0 = 412 pm, use the lennard–jones function to calculate the potential energy between pairs of xe atoms at this separation.
answer choices: -15 j/mol, -0.98 j/mol, -3.9 j/mol, 0.0 j/mol
