Is there anyway to calculate the values based off the levenspiel plot?

METHOD TO SOLVE THIS QUESTION

Given the Levenspiel plot for a gas-solid adiabatic exothermic heterogeneous reaction below, (a) Assuming you have a fluidized CSTR and a PBR containing equal weights of catalyst, how should they be arranged for this adiabatic reaction? Use the smallest amount of catalyst weight to achieve 80% conversion of A. (b) What is the catalyst weight necessary to achieve 60% conversion in a fluidized CSTR? (c) What is the catalyst weight necessary to achieve 60% conversion is a PBR? (d) Plot the rate of reaction and conversion as a function of PBR catalyst weight
