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.

What is the moles of Cl$2$ entering the reactor using the same basis of $1$kg$?$

What is the moles of gas leaving the reactor using the same basis of $1$kg$?$

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

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