Chapter 2, Problem 2.43P
Interpretation Introduction

(a)

Interpretation:

If the data support this prediction should be identified. The value of k should be determined.

Concept introduction:

A chemical reaction is carried out to convert the reactant A to the final product B. A set of data is taken by measuring the concentration of A with time (t). The author has predicted a reaction mechanism for this reaction.

The proposed reaction mechanism predicts that CA and t should be related by the expression,

lnCACAeCA0CAe=kt

where,CA=ConcentrationofA,CAe=ConcentrationofAwhent=infinity

The CA0 and CAe are given hence we can plot concentration of A versus time (t).

Interpretation Introduction

(b)

Interpretation:

If the tank volume is 125 L and there is no B in the tank at t=0, the mass of the content in tank after two hours should be calculated.

Concept introduction:

A chemical reaction is carried out to convert the reactant A to the final product B. A set of data is taken by measuring the concentration of A with time (t). The author has predicted a reaction mechanism for this reaction.

A proposed reaction mechanism predicts that CA and t should be related by the expression,

lnCACAeCA0CAe=kt

where,CA=ConcentrationofA,CAe=ConcentrationofAwhent=infinity

Interpretation Introduction

(c)

Interpretation:

The time required for the final concentration of A to reach 1.1.1.05 and 1.01 times CAe , should be estimated and the mass of B produced at each of these conditions for the reactor described in Part (b) should be calculated.

What is the composition and flowrate of the liquid stream?c. What fraction of the n-hexane (feed) ends up in the vapor phase?d. What fraction of the ethane (feed) ends up in the liquid phase?
Considering the molar flux as estimated by the Whitman two-film theory, show the relationship between the mass transfer coefficients based on concentration, and mol fraction gradients, kc and ky, respectively, is given by: ky = Ckc, where C is the total concentration. do not use chatgpt please, i did not understan from it thats why i paid for bartleby
