Thermodynamics and Thermochemistry 2 Question 10

10. $Δ H_{vap} = 30 kJ / mol$ and $Δ S_{vap} = 75 {Jmol}^{- 1} K^{- 1}$ . Find the temperature of vapour, at one atmosphere

$(2004, 1 M)$

(a) $400 K$

(b) $350 K$

(d) $250 K$

Show Answer

Solution:

$T = \frac{Δ H_{vap}}{Δ S_{vap}} = \frac{30, 000}{75} = 400 K$
