Dew$-$point Calculation$-$CLASS EXAMPLE$4$

Find the dew point temperature of a mixture containing $36\mathrm{.}28$moles of $n-$butane, $48\mathrm{.}25$moles of $n$ pentane and $15\mathrm{.}47$moles of $n-$hexane if the pressure is $2$atm.TheAntoinevaporpressureconstantsare:$InP=A-\frac{B}{T+C}$

n$-$butane $($i$)$: $A=15\mathrm{.}6782,B=2154\mathrm{.}9,C=-34\mathrm{.}42$

n$-$pentane$($j$)$: $A=15\mathrm{.}8333,B=2477\mathrm{.}07,C=-39\mathrm{.}94.$

n$-$hexane $($k$)$: A $=15\mathrm{.}8366,B=2697\mathrm{.}55,C=-48\mathrm{.}78$

$(T$ is in $K$ and $P$ is $mmHg).$ The vapor pressure equation and units are the same as in Example $3\mathrm{.}1(p$ is in $mmHg$ and $T$ is in kelvin$).$
