The 70% Conversion That Produced Only 50% Yield

Seventy percent of A reacted, but only fifty percent of the feed became the desired product B. Conversion was not the same as yield.

E-069Chemical Reaction Engineering

The Rate Constant That Increased Sixfold at 330 K

A 30 K temperature rise did not cause a 10% kinetic change. The Arrhenius relation increased the rate constant by a factor of about 6.19.

Arrhenius Temperature Dependence5–10 min

E-068Chemical Reaction Engineering

The CSTR That Needed 600 L, Not 367

The PFR-sized volume looked efficient, but the well-mixed CSTR needed 600 L to reach the same 60% conversion.

First Order Cstr Design Equation5–10 min

E-067Chemical Reaction Engineering

The Batch Reactor That Reached 63%, Not 100%

The shortcut kt=1 suggested 100% conversion after 5 minutes. The first-order batch model gave only 63.2%.

First Order Batch Reactor Kinetics5–10 min

QUICK ANSWER

What should I practice in FE Chemical Reaction Engineering?

Practice the calculations, assumptions, constraints, and failure modes that appear around this topic. Each question here is designed to test whether you can apply the concept when the obvious calculation is not the whole engineering decision.
