3.3 Calculate the size of a PFR and MFR for the following reaction:

a) A R

We assume that the reaction is elementary and takes place in the liquid phase,

XA=0.98 and, (30)

b) A 2R

We assume that the reaction is elementary and takes place in the gas phase, XA=0.90

(30)

For a) and b) we assume that:

AG298-20000 J mol-¹

AH298 -90000 J mol-¹

T = 335K

Cp are considered constant over the temperature range 298-335 K

Cao = 1 mol m 3

FAO = 50 mol s¹

For the forward reaction:

E₁ = 60000 J mol-¹

ko = 10¹⁰ S-1
