Optimum pH-119796

The word optimal pH refers to the pH at which a specific enzyme performs at its best. The structure of an enzyme is affected by pH levels.  Each enzyme has a preferred pH range; it is a range in which it performs the best.  For example, enzymes in the intestine perform optimally at a pH […]

No Hydrolysis

Hydrolysis is any reaction mechanism in which a water molecule is broken into ions and considered as an ionic species. This phrase refers to a process where water is nucleophile, such as elimination, replacement, and solvation. Biological hydrolysis is a biomolecule cleavage through which  a water molecule will break down as a large molecule into

Negative Catalysts

Catalysts are those species that enter in any chemical reaction to change the rate of any chemical reaction. In other words, we can understand that catalysts are rate changer substances of any chemical reaction. Catalysts are also of two types positive catalysts and negative catalysts. So, negative catalysts are those catalysts that change the rate

Nature of The Reactants

The rate of reaction refers to the speed that products take to form through the reactants when a chemical reaction occurs. Furthermore, it also provides essential insights into the timeframe needed to complete a reaction. For instance, the reaction rate of the combustion of cellulose in fire is much higher, and the reaction completes in

Mechanism of Enzyme Catalysis

An enzyme attracts substrates to its active site, catalyses chemical reactions that produce products, and then allows the products to dissociate. Enzyme-substrate complexes are formed when enzymes are combined with their substrates. A general mechanism of action of an enzyme is to reduce the activation energy. The activation energy of an enzyme is increased with

Mechanism of Dehydration

The synthesis of an alkene can be done by dehydration of alcohol. Water is eliminated to form a double bond in the process of dehydration of alcohol by using E1 and E2 mechanisms. The alkene is produced when the alcohol reacts with the protic acid, leading to the loss of water molecules. This is the

Meaning of Equilibrium

In a general chemical reaction, the reactants react to produce products. When an arrow indicating chemical equilibrium is marked between the reactants and products that depicts that the said reaction is reversible in nature. In a reversible chemical reaction, as soon as the products are formed they react to produce back the original products. Chemical

Limestone Calcination

Limestone is among the most extensively used and least expensive alkalising agents globally. It is frequently used in chemical operations in the form of slaked or calcium hydroxide. The heat breakdown of limestone into quick Limestone and carbon dioxide is referred to as “Limestone Calcination.” It’s often referred to as “Calcination.” Fairly basic chemical processes

Law of Mass Action

Law of mass action: In chemistry, law of mass action is defined as the theory that the rate of chemical reaction is directly proportional to the product of the concentrations of the reactants in a chemical equation.The rate of  reaction of a substance is proportional to the active mass and the reaction is directly proportional

Law of Chemical Equilibrium

Concept of chemical equilibrium Chemical equilibrium is defined as a state where both reactants and products are present in the  concentration and have no tendency to change further with time. There will be no observable changes in the properties of any particular system in the present.  The equilibrium rate of forward and backward reactions is
