r34 = ry = -k3C? = (0.008 dm³ /mol · s)C
Undesired
The specific reaction rates are given at 300 K and the activation energies are:
E, = 10,000 kcal/mol, E, = 15,000 kcal/mol and E3 = 20,000 kcal/mol
How and under what conditions (reactor type, temperature, concentrations)
should the reaction be carried out to maximise the selectivity of species B for an
entering concentration of species A of 0.4 M and a volumetric flor rate of 2.0
dm³/s ?
