Which of the following statements is true regarding adsorption isotherms? (2020)

They describe the relationship between pressure and volume.
They describe the relationship between temperature and solubility.
They describe the relationship between the amount of adsorbate and its pressure at constant temperature.
They describe the relationship between the surface area and the mass of adsorbent.

Which of the following statements is true regarding adsorption isotherms? (2020)

Step 1: Understand what adsorption means. Adsorption is when molecules stick to a surface.
Step 2: Know what an adsorbate is. An adsorbate is the substance that is being adsorbed (stuck) onto a surface.
Step 3: Know what an adsorbent is. An adsorbent is the surface that the adsorbate sticks to.
Step 4: Learn about isotherms. Isotherms are graphs or equations that show how one thing changes with another at a constant temperature.
Step 5: Combine these ideas. Adsorption isotherms show how the amount of adsorbate on the adsorbent changes with pressure while keeping the temperature the same.
Step 6: Conclude that the statement is true because it accurately describes the relationship between adsorbate, adsorbent, and pressure.
