Catalysis of homogenous and heterogeneous Catalysis can occur in both homogeneous and heterogeneous systems, each with its own characteristics and mechanisms. Here’s an overview of catalysis in homogeneous and heterogeneous systems: Homogeneous Catalysis: In homogeneous catalysis, the catalyst and the reactants are present in the same phase, typically in a solution. The catalyst is usually…
Chemisorption Chemisorption is a process in which molecules or atoms are adsorbed on the surface of a solid through chemical bonding. It involves a stronger interaction between the adsorbate (molecules or atoms) and the adsorbent (solid surface) compared to physisorption, which is based on weaker intermolecular forces. Key features of chemisorption: Applications of chemisorption: It…
Adsorption Adsorption is a process where molecules, ions, or particles adhere to the surface of a solid or liquid. It involves the accumulation of a substance at the interface between two phases, such as a solid-gas or liquid-gas interface. The substance being adsorbed is called the adsorbate, and the surface or material on which it…
Chemistry Surface chemistry is a branch of chemistry that deals with the study of phenomena that occur at the interface of two phases, such as the surface of a solid and a gas or liquid. It focuses on understanding the behavior of molecules, ions, and atoms at the surfaces and interfaces of materials. Some key…
Molecularity of a reaction The molecularity of a reaction refers to the number of molecules or particles that participate as reactants in an elementary step of a chemical reaction. It is determined by the stoichiometry of that particular step. The concept of molecularity is closely related to the reaction mechanism and the rate equation of…
Order Apologies for the confusion. Here is the suggested order for the Chemistry syllabus for the AIIMS entrance exam: Please note that this is a suggested order and you can adapt it according to your own learning style and preferences. Additionally, ensure to refer to the official AIIMS syllabus and consult appropriate study materials for…
Catalyst A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It works by providing an alternative pathway with lower activation energy, allowing the reaction to occur more readily. Catalysts play a crucial role in many industrial processes and are also significant in biological systems. Here…
Temperature Temperature is a fundamental physical quantity that measures the hotness or coldness of an object or a system. It is a scalar quantity and is typically measured in units such as Celsius (°C), Fahrenheit (°F), or Kelvin (K). Temperature is a macroscopic property that is related to the average kinetic energy of the particles…
Factors affecting the rate of a reaction The factors affecting the rate of a chemical reaction are: These factors collectively determine the rate at which a chemical reaction proceeds. It’s important to note that each reaction is unique, and the specific influence of these factors can vary depending on the reaction conditions and reactants involved.…
Rate of a reaction The rate of a reaction is a topic covered in the Chemistry syllabus of AIIMS integrated courses. The syllabus typically includes the following aspects related to the rate of a reaction: It is important to note that the specific syllabus and depth of coverage may vary depending on the course and…
