Questions & Step-by-Step Solutions

In the context of surface chemistry, what does the term 'surface area' refer to? (2020)
  • Step 1: Understand that 'surface chemistry' is the study of chemical reactions at surfaces.
  • Step 2: Recognize that 'surface area' is the total area of a surface that is exposed.
  • Step 3: Know that in surface chemistry, this area is important because it is where molecules can attach or 'adsorb'.
  • Step 4: Realize that a larger surface area means more space for molecules to attach, which increases the 'adsorption capacity'.
  • Step 5: Conclude that 'surface area' is crucial for understanding how much of a substance can stick to a surface.
