Problem 3.4 (Octave Levenspiel)

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

Problem 3.6 (Octave Levenspiel)

After 8 minutes in a batch reactor reactant (C_A0 = 1 mol/L) is 80% converted; after 18 minutes, conversion is 90%. Find a rate equation to represent this reaction.

Problem 3.11 & 3.12 (Octave Levenspiel)

Aqueous A at a concentration of C_A0 = 1 mol/L is introduced into a batch reactor where it reacts away to form product R according to stoichiometry

Aà R

The concentration of A in the reactor is monitored at various times, as shown below:

Time, min C_A, mol/m³

0 1000

100 500

200 333

300 250

400 200

(a) For C_A0 = 500 mol/m³ find the conversion of reactant after 5 hours in the batch reactor.

(b) Find the rate expression for the reaction.
