A cup of hot coffee kept on the table after pouring it. We discover after a while that the coffee has reached room temperature. Have we ever surprised, that why this occurs? The idea of thermal equilibrium seems to be come here. Thermal equilibrium describes how heat energy transfers between objects until they achieve the … Read more
Groups 3 through 12 of the periodic table contain the d-block elements, sometimes called as transition elements. These elements are essential to many industrial and chemical processes and are distinguished by the filling of the d-orbitals. Their electrical arrangements is vital to understand their physical characteristics, bonding, and chemical behaviuor. Periodic table General Electronic Configuration … Read more
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
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
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
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
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
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
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
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
