Estimate the heat of vaporization $(\frac{J}{m}ol)$ for $n-$pentane saturated at $0\mathrm{.}2$MPa by using the simplified vapor pressure equation

$(9\mathrm{.}11)$ to determine the saturation temperature and determine the slope $($the linear relationship between In$($Psat$)$ and $\frac{1}{T})$

using the Clausius$-$Clapeyron equation $(9\mathrm{.}9)$ with TR$=$Tc and PRsat$=$PC$.$
