State whether the following is true or false.
The volume advantage of a PFR over a CSTR grows with the reaction order.

  • A.False only at small scales
  • B.True
  • C.False
  • D.True only at large scales

Answer: B

A higher order makes the rate fall away more steeply with conversion, which penalises operating at the exit concentration. For a zero order reaction the two reactors need the same volume. The steeper the fall, the greater the penalty.
