A pulse of tracer was injected into a continuous reactor vessel. The following concentrations were recorded downstream of the vessel. Time (min)  0 1 2 3 4 5 6 7 8 9 10 12 14 Concentration (μmol/liter) 0 1.5 7.5 12 15 12 9 6 4.5 3.3 2.25 0.9 0 

This reactor vessel will be used for the liquid-phase, reaction shown below. A + B → C + D Where the rate law is given by: -rA = kCACB² The concentration of feed to the reactor is CA₀ = CB₀ = 0.0313 mol/liter. The rate constant is 176 ∙L²/mol² min and the reactor will be operated isothermally. 

a) Plot the E curve.  

b) Plot the F curve.  

c) Determine the mean residence time.  

d) Determine the variance of the reactor.  

e) Determine the skewness of the reactor. (1 points) 

f) Determine the conversion if we treat this vessel as an ideal CSTR with the same residence time. 

g) Determine the conversion if we treat this vessel as an ideal PFR with the same residence time.  

h) Determine the conversion predicted by the maximum segregation model.

i) Determine the conversion predicted by the Tanks in Series model.
