Use the data table and your understanding of Bond Energy to estimate the well depth (ε) of Argon. Hint: Consider the energy required to boil off 1 mole of liquid Argon already at its boiling temperature. Show all work. The energy needed to boil off one mole of liquid argon is: ∆E B =∆H∆m=6.44kJ (from the table). We can use the microscopic model to estimate the well depth. The bond energy needed to break all the bonds in the liquid Argon is given approximately by: ∆E B ~6εn atoms =6*ε*(6.02 x 10 23 mole-1 )(1 mole), so solving for the well depth:...
