Chlorobenzene $($C$)$ is produced commercially by the direct catalytic chlorination of benzene $($B$)$ at $40\backslash$deg C and $160$ kPa absolute$.$ In the process, dichlorobenzene $($D$)$ is generated as a coproduct:

C$6$H$6+$ Cl$2->$ C$6$H$5$CI $+$ HCI

C$6$H$5$CI $+$ CI$2->$ C$6$H$4$Cl$2+$ HCI

$1.$Chlorobenzene $($C$)$ has molecular weight $112\mathrm{.}56($you can find these on table B$\mathrm{.}1$ in text$),$ Benzene $($B$)$ has molecular weight $78\mathrm{.}11$ and dichlorobenzene has molecular weight of $147\mathrm{.}01.$ What is the mole fraction of C in the liquid product?

$2.$What is the mole fraction of B in the liquid product?

$3.$What is the mole fraction of D in the liquid product?

$4.$Perform a carbon balance around the reactor. What is the moles of B fed to the reactor? Choose as a basis of calculation $1$ kg of liquid leaving the reactor.

$5.$What is the moles of Cl$2$ entering the reactor using the same basis as in problem $4?$

$6.$What is the moles of gas leaving the reactor using the same basis as in question $4?$

$7.$Calculate the moles of gas out per kg of B fed to the reactor

$8.$Determine the volume in m$3$ of gas out of the reactor per kg of B fed to the reactor.
