For the liquid phase zero order irreversible reaction A → B, the conversion of A in a CSTR is found to be 0.3 at a space velocity of 0.1min-1. What will be the conversion for a PFR with a space velocity of 0.2 min-1? Assume that all the other operating conditions are the same for CSTR and PFR ?

Question

Accepted Answer

0.60. For a zero-order reaction in both CSTR and PFR, the conversion is proportional to the space velocity (or residence time). Doubling the space velocity from 0.1 to 0.2 increases the conversion from 0.3 to 0.6.
