Type 2 Home Problem -- Solution
Problems that require intermediate calculations or manipulations.

In this problem we have to find a way to relate these two reactors. At first, this question looks unsolvable, but then we recall the following relationship between k1 and k2:

Derive Equation

 

In the Homogeneous Example 1 Solution, we derived the following equation for a CSTR:

 

Our next step is to group our unknowns on one side of the equation and solve for their product:

 

Then, we use our relationship between k1 and k2:

 

k2V=3.3

 

Next, we look at our PFR design equation:

Derive Equation

 

We integrate this equation over our limits:

 

and solve for X:

 

Recalling our result for k2V that we determined above, we get:

 

X=0.72
