How Do You Calculate Recycle Stream Values in Chemical Reaction Processes?

[member 392791]

Homework Statement

Problem 12.20

Homework Equations

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