Chemical Reaction Engineering is a comprehensive text that methodically builds from fundamental reaction kinetics to advanced reactor design principles. The book guides readers through the detailed derivations of rate equations for both homogeneous and heterogeneous reactions, emphasizing how temperature, pressure, and mass transfer impact reactor performance. It also explores various reactor models—including batch, plug flow, and mixed flow—while addressing real-world challenges such as nonideal mixing, catalytic deactivation, and the complexities of fermentation processes. By interweaving theoretical derivations with practical design strategies, the text serves as an essential resource for understanding and optimizing chemical reactions in industrial applications.

Problem 1
Liquid A decomposes by first-order kinetics, and in a batch reactor $50 \%$ of $A$ is converted in a 5 -minute run. How much longer would it take to reach 75\% conversion?
Prashant Bana Numerade Educator
Problem 2
After 8 minutes in a batch reactor, reactant $\left(C_{\mathrm{A} 0}=1 \text { mol/liter) is } 80 \%\right.$ converted; after 18 minutes, conversion is $90 \%$. Find a rate equation to represent this reaction.

Problem 3
The pyrolysis of ethane proceeds with an activation energy of about 300 kJ/mol. How much faster is the decomposition at $650^{\circ} \mathrm{C}$ than at $500^{\circ} \mathrm{C} ?$

Problem 4
In a homogeneous isothermal liquid polymerization, $20 \%$ of the monomer disappears in 34 minutes for initial monomer concentration of 0.04 and also for 0.8 mol/liter. What rate equation represents the disappearance of the monomer?
Problem 5
Large central power stations (about 1000 MW electrical) using fluidized bed combustors may be built some day (see Fig. P1.2). These giants would be fed 240 tons of coal/hr ($90\%$ $\text{C}$, $10\%$ $\mathrm{H}_{2}$ ), $50 \%$ of which would burn within the battery of primary fluidized beds, the other $50 \%$ elsewhere in the system. One suggested design would use a battery of 10 fluidized beds, each $20 \mathrm{m}$ long, $4 \mathrm{m}$ wide, and containing solids to a depth of $1 \mathrm{m}$. Find the rate of reaction within the beds, based on the oxygen used.

Problem 6
A 10 -minute experimental run shows that $75 \%$ of liquid reactant is converted to product by a $1 / 2$ -order rate. What would be the fraction converted in a half-hour run?
