Question: Which of the following is a characteristic of multilayer adsorption? (2019)

Options:

  1. Occurs at low pressures only
  2. Described by the Langmuir isotherm
  3. Described by the BET theory
  4. Involves only physical adsorption

Correct Answer: Described by the BET theory

Exam Year: 2019

Solution:

Multilayer adsorption is described by the BET theory, which accounts for the formation of multiple layers of adsorbate on the adsorbent.

Questions & Step-by-Step Solutions

Which of the following is a characteristic of multilayer adsorption? (2019)
  • Step 1: Understand what adsorption means. It is the process where molecules stick to a surface.
  • Step 2: Learn about multilayer adsorption. This means that more than one layer of molecules can stick to the surface.
  • Step 3: Familiarize yourself with BET theory. This theory explains how these multiple layers form on a surface.
  • Step 4: Recognize that in multilayer adsorption, the first layer of molecules is attracted to the surface, and additional layers form above it.
