hi, Please answer all parts. i am waiting.

thanks for your help.

(b) Why would you use a differential reactor instead of an integral reactor for kinetics evaluation? [4 marks] (c) For a gas phase catalysed reaction (A3R) with the rate expression rA=kCA where k=117Lh1kgcat ?, determine the amount of catalyst needed to achieve 50% conversion of a 2000molh ' feed of pure A at 3.8atm and 106C using. (i) A packed bed reactor: [6 marks] (ii) The same packed bed reactor with a very high recycle rate. [4 marks] (iii) Why is there a difference between the mass of catalyst calculated for the two reactor set-ups?
