The elementary gas phase reaction
A--> C + 2D , rA = K ca,
It is carried out isothermally ina flow reactor with no change in pressure. The psecific reaction rate us 0.25 min^-1. A enters the reactor at a molar flow of 2 mol/min. Calculate the reactor volume to achieave 80% conversion in:
A) CSTR
B) PFR
