FAQs on Mind Map: Surface Chemistry - Chemistry Class 12 - NEET

1. What is surface chemistry?
Ans. Surface chemistry refers to the branch of chemistry that deals with the study of chemical reactions that occur at the interface of two phases, usually between a solid and a liquid or gas. It involves the understanding of the behavior of substances at the molecular level on various surfaces.
2. What are the applications of surface chemistry?
Ans. Surface chemistry has numerous applications in various fields. Some of the common applications include catalysis, corrosion prevention, electroplating, drug delivery systems, emulsions, detergents, and even the functioning of biological systems like cell membranes.
3. How do catalysts work in surface chemistry?
Ans. Catalysts in surface chemistry work by providing an alternative reaction pathway with lower activation energy. They adsorb reactant molecules onto their surface, allowing the reaction to occur more readily. The interaction between the catalyst and reactants at the surface facilitates the formation of intermediate species, which eventually leads to the desired products.
4. What is adsorption in surface chemistry?
Ans. Adsorption is the phenomenon in which molecules or ions from a gas or liquid phase adhere to the surface of a solid substance. It can be either physical adsorption or chemisorption, depending on the strength of the interaction between the adsorbate and the adsorbent. Adsorption plays a crucial role in various applications like gas masks, chromatography, and heterogeneous catalysis.
5. How does surface tension relate to surface chemistry?
Ans. Surface tension, a property of liquids, is directly related to surface chemistry. Surface tension is the force that acts at the surface of a liquid and tends to minimize its surface area. It arises due to the cohesive forces between the liquid molecules at the surface. Surface chemistry studies the behavior of these molecules and their interactions, which contribute to the surface tension phenomenon.
