A unimolecular reaction is a type of chemical reaction that involves the transformation of a single molecule into one or more products, typically occurring when the molecule has absorbed enough energy to undergo a structural change. These reactions are often described by first-order kinetics, where the reaction rate depends solely on the concentration of the single reactant molecule.

A chemical reaction is a process where substances, known as reactants, are transformed into different substances, called products, through the breaking and forming of chemical bonds. This transformation involves changes in energy and is governed by the principles of conservation of mass and energy.

Structural change refers to the dynamic process where the fundamental economic framework of a society shifts, often driven by technological innovation, globalization, or changes in consumer preferences. This transformation affects industries, employment patterns, and economic growth, necessitating policy adaptation and strategic planning to manage its impacts effectively.

First-order kinetics describes a reaction rate that is directly proportional to the concentration of a single reactant, meaning that as the concentration decreases, the rate of reaction decreases linearly. This kinetic model is commonly used to describe processes such as radioactive decay and the elimination of drugs from the body, where the rate constant remains unchanged over time.

Reaction rate is a measure of how quickly reactants are converted into products in a chemical reaction, influenced by factors such as temperature, concentration, surface area, and catalysts. Understanding reaction rates is crucial for controlling industrial processes, optimizing reaction conditions, and studying reaction mechanisms in chemistry.
