Q
Q: In the Langmuir adsorption isotherm, what does the term 'K' represent?
Solution: In the Langmuir isotherm, 'K' is the equilibrium constant that relates the concentration of adsorbate in the gas phase to the amount adsorbed on the surface.
Steps: 5
Step 1: Understand that the Langmuir adsorption isotherm is a model that describes how molecules (adsorbate) stick to a surface (adsorbent).
Step 2: Recognize that 'K' is a symbol used in this model.
Step 3: Know that 'K' represents the equilibrium constant.
Step 4: Realize that the equilibrium constant 'K' shows the relationship between the amount of adsorbate in the gas phase and the amount that is stuck to the surface.
Step 5: Conclude that a higher 'K' value means more adsorbate is sticking to the surface at equilibrium.
