Question:

What if someone suggested you could use the solution to the flow-dispersion-reactor equation, Equation (18-18), for a second-order equation by linearizing the rate law by lettering −rA=kCA2≅(kCA0/2)CA×

(1) Under what circumstances might this be a good approximation? Would you divide CA0 by something other than 2?

(2) What do you think of linearizing other non-first-order reactions and using Equation (18-18)?

(3) How could you test your results to learn whether the approximation is justified?

Equation (18-18)X=1-4q exp(Per/2)(1+q)2 exp(Per/2)-(1-q)2 exp(-Perq/2)(18-18) where q=1+4Da1/Per Da1=k, and Per-UL/Da.
