An isothermal aqueous phase reversible reaction, P ⇌ R, is to be carried out in a mixed flow reactor. The reaction rate in k.mole/m3 .h is given by, r = 0.5CP – 0.125CR. A stream containing only P enters the reactor. The residence time required (in hours) for 40% conversion of P is_________________?
Correct answer: C
Explanation
For a mixed flow reactor (CSTR), the design equation is C_A0 - C_A = r * V/F. Solving for residence time ($ au$) yields 1.60 hours.
