Document Summary
Signed____________________________________: ____/25 pts, ____/10 pts, ____/10 pts, ____/10 pts, ____/20 pts, ____/5 pts, ____/20 pts. Total 100 pts (25%) 1) the following reversible, elementary, liquid phase reaction occurs in a cstr: To begin, you need to use the conversion obtained from the energy balance. Now, you can plot this line on the x eq versus t curve (see below) Where the lines intersect is the operating temperature, t, (~ 398 k) and equilibrium conversion, x eq, (~0. 59) You want 90% of this value (as stated in the problem) X = 0. 90*x eq = 0. 90*0. 59 = 0. 53 = x. Now you can use this value in the design equation for a first-order, reversible reaction using a cstr. To get values of k and kc at 398 k, use the plots given (see below) k ~ 2. 4 s-1. Plug in values and solving for space time, . E q ui li b ri u m.
