**Langmuir Adsorption Isotherm**
The Langmuir adsorption isotherm is a model that describes the adsorption of gas molecules onto a solid surface. It is based on the assumption that the surface of the adsorbent is uniform and that adsorption occurs through a monolayer formation.
According to the Langmuir adsorption isotherm, at very high pressure, the amount of gas adsorbed reaches a constant limiting value. This phenomenon is known as saturation.
**Explanation:**
1. **Monolayer Formation:**
The Langmuir adsorption isotherm assumes that adsorption occurs through the formation of a monolayer on the surface of the adsorbent. This means that as gas molecules interact with the surface, they adhere to it and form a single layer of adsorbed molecules.
2. **Adsorption and Desorption:**
Adsorption is the process by which gas molecules bind to the surface of the adsorbent, increasing the amount of gas adsorbed. Desorption, on the other hand, is the process by which adsorbed molecules detach from the surface and return to the gas phase.
3. **Equilibrium:**
At equilibrium, the rate of adsorption is equal to the rate of desorption. This means that the amount of gas adsorbed remains constant over time.
4. **Saturation:**
At very high pressures, the surface of the adsorbent becomes fully covered with adsorbed gas molecules. This means that all available adsorption sites are occupied, and further adsorption becomes unlikely. The amount of gas adsorbed reaches a constant limiting value, known as the saturation coverage or maximum adsorption capacity.
5. **Equilibrium Constant:**
The Langmuir adsorption isotherm can be represented by an equation that relates the pressure of the gas to the amount of gas adsorbed. This equation includes a constant known as the equilibrium constant, which depends on the temperature and the nature of the adsorbent and adsorbate.
6. **High Pressure Limit:**
As the pressure increases, more gas molecules are available to interact with the adsorbent surface. However, at very high pressures, the adsorption sites become saturated, and the amount of gas adsorbed reaches a constant value. Further increase in pressure does not result in additional adsorption.
Therefore, according to the Langmuir adsorption isotherm, at very high pressure, the amount of gas adsorbed reaches a constant limiting value. This is due to the saturation of the adsorption sites on the surface of the adsorbent.
