Hello,
I am having some difficulty with levenspiel plots, in particular when dealing with a CSTR and when the reaction rate is increasing with conversion. I will give an example plot to demonstrate my point.
Assume we are trying to find the volume of a CSTR necessary to reach a conversion of X = 0.5, with the levenspiel plot given below
What I wonder, is how do I figure out what area should be taken, and why? I initially thought it would be the one in green, but I am missing something important here as far as how to use the levenspiel plot. When it is the other way around (reaction rate is decreasing with temperature), I can figure it out usually, but I seem to be missing something subtle.
