# Recycle Stream with Reaction

Problem 12.20

## The Attempt at a Solution

For this problem, I am having a hard time getting any values for the streams, so I am stuck at stream G and K and can't figure out how much is going into G since I don't know the liquid recycle stream. I don't know how to use that relationship with the conversions to get the extents of reaction, which is what I am thinking is needed.

Let RL represent the number of moles per hour of recycle toluene. What is the total rate of toluene feed to the mixer? In terms of RL what is the rate of H2 fed to the reactor? What is the rate of CH4 fed to the reactor?
