$7-5.$ Use the data in Problem $7-4$ to calculate $S$ if one mole of ethene is heated from $300K$ to $600K$ at constant pressure. Assume ethene behaves ideally.

Data from problem $7-4$:

The molar heat capacity of $C_2{H}_4(g)$ can be expressed by

$\frac{?}{\text{b}\text{a}\text{r}}(C{)}_V\frac{T}{R}=16\mathrm{.}4105-\frac{6085\mathrm{.}929(K)}{T}+\frac{822826K^2}{T^2}$

pver the temperature range $S300K600K300K.$ Calculate $Sif$ one mole $of$ eth reated from $300Kto600Kat$ constant volume.
