Question

non-reverse liquid phase reaction A>R

CAo=4mol/L, space time=120/hr, k=0.2[mol/L*sec^2]^0.5

How I know conversion A at each reactor?

1) PFR

2) CSTR

Answer 1

Please note that in the question it is given that Space time = 120/ hr , but looking at the unit we can understant that the given quantity is actually space velocity and not space time.

[ unit of space time = (time)

unit of space velocity = (time^-1) ]

Hence we have C_A0 = 4 mol/L

k = 0.2 mol^0.5/ L^0.5 sec

space velocity, v = 120/hr = (120/3600) sec^-1 = 0.03333 sec^-1

space time
