The second-order, elementary liquid-phase reaction 2A→k1AB is carried out in a nonideal CSTR. At 300 K, the specific reaction rate is k_1A = 0.5 dm³ / mol · min. In a tracer test, the tracer concentration rose linearly up to 1 mg / dm³ at 1.0 minutes and then decreased -linearly to zero at exactly 2.0 minutes. Pure A enters the reactor at a temperature of 300 K.
a. Calculate the conversion predicted by the segregation and maximum mixedness models.
b. Now consider that a second elementary reaction also takes place A+B→k2CC,k2C=0.12 dm³/mol ⋅ min Compare the selectivity S˜B/C predicted by the segregation and maximum mixedness models.
