Transcribed Image Text:Homework example:
An irreversible gas-phase reaction is carried out in a batch reactor at 25° C. The
reaction is A + B → C The rate of disappearance of reactant A is given by the
following function
(-TA) = KCACB mol/m³s, where k = 3.5 x 10-5 m³/mol s
The reactor is filled with an equal number of moles of A and B. The initial
concentration of A is CAO = 50.0 mol/m³. Calculate the fractional conversion of A
after 500 s for the following three types of batch reactors. Assume ideal gases.
a. Constant-volume reactor
b. Constant-pressure reactor
c. Variable-volume reactor where V = V0 (1 + 0.001)
Answer:
a. Constant volume
Xa=0.467
Xa=0.509
b. Constant pressure
c. Variable volume and pressure
X=0.415
