We saw above that these are: What would the corresponding expression be for a batch reactor?Instead of Comparing numerically the numbers for different cases, we can easily visualize the reactor volume in what is called 1/r-plots (or also Levenspiel-plots )...22ChE 400- Reactive Process EngineeringChEChE400400--Reactive Process EngineeringReactive Process Engineering1/r-PlotsLet s look at the PFR first:00()AXAPFRAAdXVFrX = We need 1/r(X) -> let s first look at r(X)!
