(E6-5.6)
(5) Mole balance on 0,:

(E6-5.7)

The entering molar flow rates, F,o. along with the entering temperature. To, and
preswre, Po(CTo = Po/RTo), are specified as are the specific reaction rates kq [e,g.,
klN0 = 0.43 (dm3/mol)l.5/s, k2N2 = 2.7 dm3/m01* s, etc.]. Consequently, Equations
(E6-5.1) through (E6-5.8) can be solved simultaneously with an ODE solver i(e.g.,
POLYMATH, MAmAB).
