The primary purpose of chemical reactions is to transform reactants into products through the breaking and forming of chemical bonds. These transformations lead to changes in properties and functionality, making chemical reactions foundational to countless processes in nature, such as metabolism, cellular respiration, and photosynthesis. In industry, chemical reactions enable the synthesis of new materials and compounds, driving advancements in pharmaceuticals, energy production, and agriculture. Thus, they are vital for both biological systems and technological applications.
