rate of reaction

The rate of reaction refers to how quickly a chemical change happens, typically measured by the amount of product formed or reactant used up over time. It indicates how fast the molecules are reacting with each other. Factors like temperature, concentration, surface area, and catalysts can influence the rate—higher temperature or concentration usually speeds up reactions. Understanding the rate helps in controlling processes in industries like manufacturing, medicine, and environmental management, ensuring reactions occur at desired speeds for efficiency and safety.
