Factors affecting reaction rates

A 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 […]

Introduction 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

In 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

The Brownian movement is named after Robert Brown, a Scottish botanist who was the first to study these vibrations (1827). Brown was looking into the pollen grain fertilisation of a newly found species of flowering plants when he spotted a fast rhythmic movement of microparticles inside the pollen grains held in liquid underneath the microscope.

Chemical kinetics is one of the essential branches of physical chemistry because it deals with the study of chemical reaction rates. In simpler words, you can compare it to thermodynamics, which is concerned with the direction in which a reaction takes place. Chemical kinetics is a clock, whereas thermodynamics is an arrow in time.  Kinetics

Displacement reactions are chemical reactions in which one compound replaces another. In these reactions, the reactants are displaced from their original position. Hence, it is widely accepted that displacement reactions are chemical reactions that occur when one substance replaces another through the displacement process. Furthermore, displacement reactions can occur in many different reactions, including hydrolysis,

The Optimum Temperature And PH For The Action Of An Enzyme It is important to know the pH range of each enzyme. It is usually close to neutral or neutral for most enzymes to work at their best. In a pH range of 5-7, the enzyme activity is said to be maximum. Alternatively, some enzymes

Chemical reactions, in general, show an increase in the rate of reaction for an increase in temperature. For example, it takes about 6-12 minutes to boil 1 liter of water at 100°. However, when left in the open at room temperature, the same amount of water may take hours to evaporate. This is because water

Reaction rate: Chemical reaction at a pace is referred to as the reaction rate. It’s most commonly represented as the concentration (amount per unit volume) of a product formed in a unit of time or the concentration (amount per unit volume) of a reactant consumed in a unit of time. It is also measured as

The quantitative approach of the reactants or products involved in a reaction is referred to as chemical stoichiometry. The term “stoichiometry” comes from the Greek words “stoikhein” – which means element, and “metron”, which means measure. Jeremias Richter, a German chemist, discovered the term “stoichiometry.” Stoichiometry is defined as determining the reactants and the products
