Activation energy is a notion in chemistry that was proposed in 1889 by a Swedish scientist named “Svante Arrhenius.” The lowest quantity of energy needed by chemical reactants to activate a chemical reaction is referred to as activation energy. The activation energy is sometimes described as the smallest amount of energy necessary to start a […]

Activation energy, Chemical Kinetics, Chemistry, Class 11, IIT JEEDefinition Activation Energy, in chemistry, is the base measure of energy needed to enact atoms or particles to a condition in which they can go through a chemical or physical change. The Activation Energy is the distinction in energy content between atoms or particles in an initiated or change state setup and the comparing atoms

Activation energy, Chemical Kinetics, Chemistry, Class 11, IIT JEEThe minimum amount of energy required to bring atoms or molecules to a state where they can execute a chemical transformation or physical transport is known as activation energy in chemistry. In transition-state theory, the activation energy is the difference in energy content between molecules or atoms in an activated or transition-state configuration and their
Introduction All gaseous atomic particles have a movement comprising random speed and direction. The average velocity of gaseous particles can be procured by taking the square root of the average velocities, i.e., the root mean square velocities of the gas particles. The root means square velocity has two considerations: Molecular weight Temperature. Moreover, velocity is

Chemical Kinetics, Chemistry, Class 11, Collision theory, IIT JEEThis study material notes on root mean square velocity defines root mean square velocity and the parameters on which it depends. The root mean square velocity of particles in a gas is calculated using the square root of the average velocity-squared of the individual molecules in the gas. The root-mean-square speed addresses both molecular weight

Chemical Kinetics, Chemistry, Class 11, Collision theory, IIT JEEIntroduction The square root of the aggregate velocity-squared of the molecules in a gas is the root mean square speed of gas. Towards the end of the 19th century, scientists put forth a theory on the properties of gases based on a few assumptions. These basic ideas and assumptions formed the basis for the Kinetic
The meeting of two or more point masses in split-second contact is a collision of point masses. The meeting could be due to excitation or the natural motion of the point masses. Collision may be defined as the short duration interaction between two or more than two point masses simultaneously leading to change in motion

Chemical Kinetics, Chemistry, Class 11, Collision theory, IIT JEEA catalyst is a substance that overall changes the rate of reaction without being consumed in a reaction. In Chemistry, catalysts are widely used to enhance the rate of any chemical reaction without changing the product. The name catalyst was given by Berzelius in 1835. A large number of catalytic reactions are known in chemistry

Chemical Kinetics, Chemistry, Class 11, Factors affecting reaction rates, IIT JEEIntroduction When a chemical process achieves equilibrium, the equilibrium constant (typically indicated by the symbol K) offers information about the relationships between the reacting species. It is worth noting that various distinct categories of kinetic parameters give links between balanced chemical reactions. Chemical equilibrium Chemical equilibrium is an important aspect of the biological and chemical

Chemical Kinetics, Chemistry, Class 11, Factors affecting reaction rates, IIT JEEIn other words, a catalyst is a substance that accelerates the velocity of a chemical reaction without changing the nature of the substance itself. A lower-activation-energy alternative pathway becomes available in the presence of a catalytic agent. Because less energy is required for success in collisions, more collisions are successful. It is possible to retrieve
