Question

Estimate the normal boiling point of 2-methylheptane using Trouton's rule [estimating that ?S is approximately 87-88 J/(K?mol)] assuming that the enthalpy of vaporization, Hvap = 33.26kJ/mol , remains relatively constant. Express your answer in kelvins to three significant figures. Estimate the normal boiling point of 2-methylheptane using Trouton's rule [estimating that ?S is approximately 87-88 J/(K?mol)] assuming that the enthalpy of vaporization, Hvap = 33.26kJ/mol , remains relatively constant. Express your answer in kelvins to three significant figures.

Explanation / Answer

delta S = delta H/boiling temp

i.e. boilint temp = delta H/ delta S = 33260/88 = 377.955 K
