key term - Selectivity

Definition

Selectivity refers to the ability of a catalyst to favor one reaction pathway over others, leading to the preferential formation of a specific product. This property is crucial in industrial processes as it can significantly impact the efficiency and economic viability of chemical reactions. A highly selective catalyst helps minimize by-products, optimize yield, and reduce waste, thereby enhancing sustainability in chemical manufacturing.
