Chemisorption Chemisorption is a process of adsorption in which a chemical reaction occurs between the adsorbate (molecules or atoms being adsorbed) and the surface of the adsorbent (the material on which adsorption takes place). It involves the formation of chemical bonds between the adsorbate and adsorbent, resulting in the creation of a new compound or…
Adsorption The AIIMS (All India Institute of Medical Sciences) entrance exam for Chemistry does not have a specific syllabus topic for Adsorption. However, a general understanding of the concept of adsorption may be helpful in some areas of Chemistry. Here is a concise summary of the concept of adsorption: Adsorption refers to the process in…
Surface Chemistry Surface Chemistry is a branch of chemistry that deals with the study of phenomena occurring at the interface of two phases, such as solid-gas, solid-liquid, or liquid-gas. It focuses on the behavior and properties of surfaces, interfaces, and the interactions that take place at these boundaries. Key topics covered in Surface Chemistry include:…
Molecularity of a reaction The molecularity of a reaction refers to the number of molecules or particles that participate as reactants in an elementary reaction. It is a concept used in chemical kinetics to describe the overall reaction rate and mechanism. Molecularity can have values of 1, 2, or 3, representing unimolecular, bimolecular, and termolecular…
Order The syllabus for the Chemistry section of the AIIMS entrance exam can vary slightly from year to year. However, here is a general order and breakdown of topics that are typically covered: Keep in mind that this is a general outline and the actual syllabus may vary. It is always recommended to refer to…
Catalyst A catalyst is a substance that increases the rate of a chemical reaction by providing an alternative reaction pathway with lower activation energy. It participates in the reaction but is not consumed or permanently altered in the process, allowing it to be used repeatedly. Catalysts can facilitate reactions by providing a surface for the…
Temperature Temperature is a measure of the average kinetic energy of the particles in a substance or system. It represents the degree of hotness or coldness of an object or environment. In scientific terms, temperature is often measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K). Here are some key points about temperature: Understanding…
Factors affecting the rate of a reaction Several factors can affect the rate of a chemical reaction: It’s important to note that the influence of each factor may vary depending on the specific reaction and the conditions in which it occurs. The factors affecting the rate of a chemical reaction, as covered in the AIIMS…
Rate of a reaction The rate of a reaction refers to how quickly a chemical reaction occurs, specifically the change in concentration of reactants or products over time. It is often expressed as the rate of disappearance of a reactant or the rate of formation of a product. The rate of a reaction can be…
Chemical Kinetics Chemical kinetics is the branch of chemistry that deals with the study of the rates at which chemical reactions occur and the factors that influence these rates. It focuses on understanding the mechanisms by which reactants are transformed into products, as well as the factors that affect the speed of these reactions. Key…
