Newton’s Law of Cooling

A hot cup of tea gradually cools to room temperature when left on the table. Have you ever questioned how and why this occurs? Newton’s Law of Cooling, which was developed by Sir Isaac Newton, governs the cooling process. This law describes the relationship between an object’s rate of cooling and the temperature differential between … Read more

Collision Theory of Chemical Reactions

Reactant molecules combine to create new products, which are known as a chemical reaction. However, have we ever thought the true causes of molecular reactions? What causes some reactions to occur more quickly than others? A correct and rational explanation for these questions can be found in the Collision Theory of Chemical Reactions. Molecules What … Read more

Heat Transfer

Why a metal spoon becomes heated when left in a hot cup of coffee? Or why, despite the fact that both are at the same temperature, walking barefoot on tiles in the winter seems colder than walking on a carpet? All of these commonplace occurrences are connected to heat transfer or the movement of heat … Read more

Temperature Dependence of the Rate of a Reaction

The rate of a reaction in chemistry indicates how quickly reactants are transformed into products, and temperature is one of the most significant factors influencing reaction rates. In general, the rate of reaction increases as temperature rises because molecules move more quickly at higher temperatures, which causes more frequent and intense collisions between reactant molecules. … Read more

Change of State of Matter

There are three physical states of matter: solid, liquid, and gas. Under specific temperature and pressure conditions, these states can be used interchangeable. A change in state of matter is the process of changing from one state to another. Changes in the energy levels and intermolecular forces of the particles within a material cause this … Read more

Integrated Rate Equations

The rates at which chemical reactions take place. Some are very slow, like iron rusting, where as others are very fast, like an explosion. Chemical kinetics is the study of reaction rates and the variables influencing them. Integrated rate equations, which show us how the concentration of reactants varies over time, are one of the … Read more

Principle of Calorimetry

The Calorimetry measures the quantity of heat that is transferred between two or more bodies or within a system as a result of phase changes, chemical reactions, or temperature variations. The law of conservation of energy, which asserts that energy can only be transformed from one form to another and cannot be created or destroyed, … Read more

Factors Affecting Reaction Rate

The speed at which reactants are transformed into products is known as the rate of a chemical reaction. Numerous variables that affect the frequency and energy of molecular collisions affect this rate. Controlling and optimising reactions in biological systems. Factors Affecting Reaction Rate:Nature of Reactants Reaction speeds are strongly influenced by the chemical composition of … Read more

Specific Heat Capacity

Specific heat capacity is a basic concept in thermodynamics and it plays a major role in heat transmission in different substances. It explains how much heat is necessary to change the temperature of a particular substance and is extensively employed in physics, chemistry, and engineering. Heat transmission Definition of Specific Heat Capacity Specific heat capacity, … Read more

SN1 and SN2 Reactions

Nucleophilic substitution reactions are essential processes in organic chemistry that occur when one nucleophile (A chemical species that donates an electron pair to create bonds is known as a nucleophile. Any molecule or ion that has at least one pi bond or a free pair of electrons can function as a nucleophile. Electron SN1 and … Read more
