The gas-phase reaction A + B C + 2D Will be conducted in an isothermal PBR. The reaction follows an elementary rate law. In order to ensure that A will be completely consumed B is fed in 5% excess.

a)Sketch the pressure versus the catalyst weight.

b)Sketch the conversion of A versus catalyst weight.

c)Sketch the concentrations of A, B, C and D versus catalyst weight.

d) Write all of the equations required to determine the catalyst mass required for a 99.9% conversion of A. Dont forget to define your initial and final conditions wherever necessary.
