Hi, I was asked by my senior to find out what this graph is and how to use it. No details were given as to where they found it.(adsbygoogle = window.adsbygoogle || []).push({});

I know already that this is used to compare CSTRs and PFRs performance for first order reactions, but I can't deduce what the expressions D_{d}/(v_{x}L) and kL/v_{x}are for and what the variables represent.

Thanks a lot!
