Chemical Reaction Engineering

We wish to explore various reactor setups for the transformation of A into R. The feed contains 99%A,1%R; the desired product is to consist of 10%A,90% R. The transformation takes place by means of the elementary reaction A+RR+R with rate constant k=1L/(mol. Min). The concentration of active materials is CA0+CR0=1mol/L throughout. What reactor holding time will yield a product in which CR1=0.9mol/L a. Write expression for the rate of reaction b. Estimate rate of reaction for various values of CA in the reactor c. in a plug flow reactor d. in a stirred flow reactor e. in a minimum-size setup without recycle
