Chemical Kinetics

Consider the following example of a straightforward chemical reaction in which reactant A is transformed into product B using the equation below.                                   A B   The change in concentration of A as a function of time can be used to calculate the rate of a reaction. The rate at which A disappears is also proportional […]

The mechanism through which the state of a liquid converts into the condition of a vapour is known as vaporisation. As the temperature rises, the kinetic energy of the molecules rises as well. Because of the increase in kinetic energy, the force of attraction between the molecules decreases. As a result, they escape into the

If one of the reaction products is also a catalyst for the same or a related process, the reaction is referred to as autocatalytic. This type of reaction is referred to as an autocatalytic reaction. A group of chemical reactions is considered to be “collectively autocatalytic” if a number of them provide catalysts for enough

Different chemical reactions occur when two or more reactants interact in controlled environments. The use of catalysts is one of the essential parts of multiple chemical reactions to increase the yield and rate of reaction. Homogeneous catalysis is one such exclusive type of chemical reaction. The catalyst and different reactants remain in the same phase

What Is Stoichiometry? Stoichiometry is the evaluation of products and reactants that are part of a chemical reaction. The term “stoichiometry” is derived from the Greek words, “stoicheion” and “metry” meaning element and measuring, respectively. Stoichiometry Formulas The law of conservation of mass is the base concept of stoichiometry; the mass of reactants is equal

A catalyst is a substance that increases the rate of a reaction without changing itself in terms of mass and composition. Take this chemical reaction, for example: 2KClO32KCl+3O2.  In this reaction, potassium chlorate is decomposed into potassium chloride and oxygen. This is a slow reaction that occurs in the temperature range of 653-873K. If we

Reaction Kinetics is the study of the rates at which chemical reactions or processes take place. One of the most advanced research in physical chemistry is being conducted at this time. Engineers and scientists can use the information about these factors affecting the rate of a chemical reaction to economically scale up the reactions to

The ratio of the distance travelled by the analyte to the distance travelled by the solvent front on a chromatogram is known as the retardation or retention factor (Rf) value. Rf values Definition and Explanation The mobility of analytes with mobile solvents differs from that of analytes added to stationary phases in chromatographic methods (phases).

It is pretty well known that chemistry and biology go hand in hand, and thus, chemical reactions are an essential part of chemistry. Thus, it is essential to have a clear-cut concept about reactions, how they progress, and their rate. Different reactions have different rates of progression, and it all depends on their mechanism and

Rate of a reaction Introduction The rate of reaction definition refers to the speed that products take to form through the reactants when a chemical reaction occurs. Further, it also provides essential insights into the time frame needed to complete a reaction. For instance, the reaction rate of the cellulose’s combustion in fire is much
