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…
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…
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 transform into products and the factors that affect the speed of these reactions. Key concepts in chemical…
EMF Electromotive Force (EMF) is a term used in the field of physics and electrical engineering. It refers to the potential difference or voltage developed between two points in an electrical circuit or an electrochemical cell. EMF is typically represented by the symbol “E” and is measured in volts (V). In the context of an…
Laws of electrolysis The AIIMS (All India Institute of Medical Sciences) entrance exam is a prestigious medical entrance examination in India. While I can provide you with information on the topic of “Laws of Electrolysis” in the Chemistry syllabus, it’s important to note that the syllabus for the AIIMS entrance exam may vary from year…
Redox reactions Short for oxidation-reduction reactions, are chemical reactions in which there is a transfer of electrons between species. In these reactions, one species undergoes oxidation (loses electrons) while another species undergoes reduction (gains electrons). This transfer of electrons is accompanied by changes in the oxidation numbers of the elements involved. Key concepts related to…
