About Surface Chemistry (JEE Main, Class11th)

What is Surface Chemistry ?

Surface chemistry is the branch of chemistry that deals with the study of chemical reactions, phenomena, and behaviour that occur at the interfaces between two phases, such as solid-liquid, solid-gas, or liquid-gas interfaces. It focuses on understanding the unique properties and processes that arise at the surface or interface of materials, which can differ significantly from their bulk properties. Surface chemistry explores topics such as adsorption, desorption, surface reactions, catalysis, surface tension, wettability, self-assembly, and the characterization of surfaces. It plays a crucial role in various fields, including materials science, nanotechnology, catalysis, colloid science, and bio interfaces, and has important applications in areas such as chemical manufacturing, environmental science, and medicine.
