Hammond's postulate suggests that the transition state of a reaction resembles the structure of the nearest stable species. In exothermic reactions, the transition state is closer to the reactants, while in endothermic reactions, it is closer to the products.

Hammond's postulate

The transition state in a chemical reaction is a high-energy, unstable arrangement of atoms that represents the point of maximum energy along the reaction path. It is crucial for understanding reaction mechanisms as it determines the rate and feasibility of the reaction.

stable species

Exothermic reactions are chemical processes that release energy, usually in the form of heat, to their surroundings, resulting in an increase in temperature. These reactions are crucial in various applications, from industrial energy production to biological processes like respiration.

exothermic reactions

Endothermic reactions are chemical processes that absorb heat from their surroundings, resulting in a decrease in temperature of the environment. These reactions require an input of energy to proceed, often leading to products that have higher energy than the reactants.

endothermic reactions

Reactants are the initial substances involved in a chemical reaction, which undergo transformation to produce products. Understanding the nature and properties of reactants is crucial for predicting the outcome of chemical reactions and for the synthesis of new compounds.

reactants

Products are tangible or intangible items offered to a market to satisfy a want or need, encompassing goods, services, and experiences. They are central to business strategies, requiring careful consideration of design, quality, branding, and lifecycle management to meet consumer expectations and achieve competitive advantage.
