The boiling temperature of cyclohexane, C₆H₁₂, is 354 K. Use Trouton's rule to estimate the enthalpy of vaporization of cyclohexane.

Question

Quizplus · Accepted Answer

Trouton's rule states that the enthalpy of vaporization (ΔHvap) of a liquid at its boiling point is roughly 88 J/mol·K. Given the boiling temperature of cyclohexane is 354 K, ΔHvap can be estimated as ΔHvap = 88 J/mol·K * 354 K = 31152 J/mol, which is approximately 31.2 kJ/mol, making option D the closest answer.

The Boiling Temperature of Cyclohexane, C6H12, Is 354 K

The Boiling Temperature of Cyclohexane, C₆H₁₂, Is 354 K
