We wish to explore various reactor setups for the transformation of A into R. The feed contains 0.9 mol/L of A, 0.2 mol/L R; the desired product is to consist of 1.8 mol/L R. The transformation takes place by means of the elementary reaction with rate constant k = 0.1 L/mol. min. 2A+R+R+R a) What is the rate expression for this reaction? b) What is the concentration of A when 1.8 mol/L R has been produced in the reaction? c) The following table has been produced to assist with the calculation. What is the missing value? (0) £ CA mol/L 0.9 0.8 0.65 0.5 0.3 0.2 0.15 0.1 d) What reactor holding time will yield a product in which C₂ = 1.8 mol/L. You are asked to provide answers for any four of the five below options. Please show your calculations.

Question
We wish to explore various reactor setups for the transformation of A into R. The feed contains 0.9 mol/L of A, 0.2 mol/L R; the desired product is to consist of 1.8 mol/L R. The transformation takes place by means of the elementary reaction with rate constant k = 0.1 L/mol.min. 2A +R → R+R a) What is the rate expression for this reaction? b) What is the concentration of A when 1.8 mol/L R has been produced in the reaction? c) The following table has been produced to assist with the calculation. What is the missing value? CA -1/rA mol/L 0.9 61.7284 0.8 39.0625 0.65 33.81234 0.5 40 0.3 79.36508 0.2 ? 0.15 261.4379 0.1 555.5556 d) What reactor holding time will yield a product in which C₂ = 1.8 mol/L.
