Question

In the experiment, a gas-phase, elementary reaction

A → B + 2C

is carried out in an isothermal flow reactor without pressure change. In the operation, pure A enters the reactor at 1010.2 kPa and 400 K with a molar flow rate of 2.5 mol/min. From literature, it was found that the specific reaction rate at 323 K is 0.0001 min-1 and the activation energy is 85 kJ/mol. Calculate yA0, δ, ε and then the volume to achieve 80% conversion in

1. a plug-flow reactor

and

2. a continuous-stirred tank reactor.

Gas constant: R = 8.314 J/(K∙mol) = 8.314 kPa • dm3/mol/k.

Equation for integration use: (see photo)
