**Interphase Mass Transfer Diagram Analysis**

**Question 7:**

In the following interphase mass transfer diagram, concentrations are expressed as mole fractions (y for gas, x for liquid).

**Diagram Description:**

The diagram is divided into two main phases: Gas and Liquid, separated by an interface.

- **Y-axis:** Concentration of diffusing species A
- **X-axis:** Distance across the phases

**Key Points in the Diagram:**
- In the Gas phase, the concentration starts at \( y_{AG} \) and increases towards the interface, reaching \( y_{Ai} \).
- In the Liquid phase, the concentration starts at \( x_{AL} \) and decreases towards the interface, reaching \( x_{Ai} \).
- \( y_{AG} \) is the initial concentration in the gas phase, and \( x_{AL} \) is the initial concentration in the liquid phase.
- \( y_{Ai} \) and \( x_{Ai} \) are the concentrations at the interface in the gas and liquid phases, respectively.

**Questions:**

a) Does this represent:
   - i) Gas to liquid
   - ii) Liquid to gas transport

b) Is Henry’s law constant (H):
   - i) H > 1
   - ii) H < 1
   - iii) H = 1
