SUMMARY
The average S-F bond enthalpy in sulfur hexafluoride (SF6) can be calculated using the standard enthalpy of formation values for SF6(g), sulfur (S(g)), and fluorine (F(g)). The values are -1100 kJ/mol for SF6, 275 kJ/mol for S, and 80 kJ/mol for F. The correct calculation for the average S-F bond enthalpy is derived from the equation: average bond enthalpy = -ΔH of formation / number of bonds, resulting in an average bond enthalpy of 183.33 kJ/mol for the S-F bond.
