Overview
Surface Chemistry is the study of chemical processes occurring at interfaces between different phases—such as solid-liquid, solid-gas, and liquid-liquid boundaries. This branch of chemistry is crucial for understanding everyday phenomena like water droplets forming spheres, mosquitoes walking on wat
Key Concepts
Adsorption is a surface phenomenon where
Adsorption is a surface phenomenon where molecules accumulate on the surface of a solid (adsorbent) due to free valency or residual forces. The substa
Physical adsorption (physisorption) involves weak van
Physical adsorption (physisorption) involves weak van der Waals forces between adsorbent and adsorbate. It is rapid, non-specific, occurs at low tempe
Adsorption depends on multiple factors
Adsorption depends on multiple factors: (1) Surface area of adsorbent—larger surface area increases adsorption; (2) Nature of adsorbate—easily liquefi
The Freundlich equation
The Freundlich equation, x/m = kp^(1/n), quantitatively describes adsorption at constant temperature. Here, x is the amount of adsorbate adsorbed, m i
A catalyst is a substance
A catalyst is a substance that alters the reaction rate without undergoing permanent chemical change. The phenomenon involving catalyst action is call
