The gas phase reaction 2A ⇌ B is carried out in an isothermal plug flow reactor. The feed consists of 80 mole % A and 20 mole % inerts. If the conversion of A at the reactor exit is 50%, then CA/CA0 at the outlet of the reactor is _______________________?
Correct answer: B
Explanation
The mole fraction of A at the outlet is calculated using the initial composition and conversion. The ratio CA/CA0 equals 1 - X_A.
