Q$1$ Using the Peng$-$Robinson state equation in $400$ K and $80$ bar for propan, calculate the deviation functions for internal energy, enthalpy and entropy.

O$2$Estimate the molar volume and intensity of a binary mixture containing $30\%$mol propane $(1)$ and $70\%$n$-$b$$tan $(2)$ in $350$ k and $3$bar. ACCEPT THE Mix

Q$3$ The feeding of $80$ mol HCL$,19\mathrm{.}5\%$O$2$ and $0\mathrm{.}5\%$N$2$ is fed to the reactor operating in $700$ k and $1$ bar. The following reaction in the reactor

is happening. Estimate the composition of the balance mixture. The reaction temperature depends on temperature

$2$HCL$+0\mathrm{.}5$ O$2=$ CL$2+$H$2$O
