(a)

Interpretation Introduction

Interpretation:

To develop Rule of thumb: Solubility of a solid in a liquid solvent increases with increasing T.

Concept Introduction:

The given rule of thumb is based on case II binary SLE behavior.

Let the solid be pure species 1 and the Liquid solvent be species 2.

Then x1=ψ1andψ1=expΔH1slRTm1(TTm1T)

(b)

Interpretation Introduction

Interpretation:

To develop Rule of thumb: Solubility of a solid in a liquid solvent is independent of the identity of the solvent species

Concept Introduction:

The given rule of thumb is based on case II binary SLE behavior.

Let the solid be pure species 1 and the Liquid solvent be species 2.

Then x1=ψ1andψ1=expΔH1slRTm1(TTm1T)

(c)

Interpretation Introduction

Interpretation:

To develop Rule of thumb: Of 2 solids with roughly the same heat of fusion, that solid with the lower melting point is the more soluble in a given liquid solvent at a given T

Concept Introduction:

The given rule of thumb is based on case II binary SLE behavior.

Let the solid be pure species 1 and the Liquid solvent be species 2.

Then x1=ψ1andψ1=expΔH1slRTm1(TTm1T)

(d)

Interpretation Introduction

Interpretation:

To develop Rule of thumb: Of 2 solids with similar melting points, that solid with the smaller heat of fusion is the more soluble in a given liquid solvent at a given T

Concept Introduction:

The given rule of thumb is based on case II binary SLE behavior.

Let the solid be pure species 1 and the Liquid solvent be species 2.

Then x1=ψ1andψ1=expΔH1slRTm1(TTm1T)

Chemical Engineering Use the psychrometric chart and demonstrate the linear interpolation method to obtain -0.52 KJ/KgDA.  This is the enthalpy deviation.   The exercise is uploaded below.
Chemical Engineering  Use the psychrometric chart. The remaining curves on the psychrometric chart are almost vertical and convex to the left, with labeled values (on Figure 8.4-1) of 0.05, 0.1, 0.2, and so on. (The units of these numbers arekJ/kg DA). Thesecurves are usedto determine theenthalpyof humid air that is not saturated. The procedure is as follows: (a) locate the point on the chart corresponding to air at its specified condition; (b) interpolate to estimate the enthalpy deviation at this point; (c) follow the constant wet-bulb temperature line to the enthalpy scale above the saturation curve, read the value on that scale, and add the enthalpy deviation to it. Also, you will see the exercise on the piece of paper.
Calculate the permeability of the bed of ion-exchange particles in Example 11.1.
