Questions & Step-by-Step Solutions
Which of the following is an example of a physical adsorption process?
Step 1: Understand what physical adsorption means. It is when molecules stick to a surface without any chemical reaction.
Step 2: Learn about gas chromatography. It is a method used to separate different components of a gas mixture.
Step 3: Identify the role of the stationary phase in gas chromatography. The stationary phase is the material that the gas molecules stick to.
Step 4: Recognize that in gas chromatography, the separation of components happens because they have different strengths of attraction to the stationary phase.
Step 5: Conclude that gas chromatography is an example of a physical adsorption process because it relies on the sticking of gas molecules to a surface without changing their chemical structure.
