catalisadas

Catalisadas is the feminine plural form of the past participle of the verb catalisar (to catalyze) in some Romance languages, and it is used as an adjective to describe reactions or processes that have been accelerated by a catalyst. In this sense, a catalisada reaction is one that proceeds faster than its non-catalyzed counterpart due to the presence of a substance that provides an alternative reaction pathway with a lower activation energy.

In chemistry, catalysis involves catalysts that are not consumed in the overall reaction; they emerge from the process unchanged or regenerated. Catalisadas reactions can be classified by the nature of the catalyst: heterogeneous catalysts (different phase from reactants, such as a solid catalyst in a liquid reaction), homogeneous catalysts (same phase as reactants), and enzymatic catalysts (biological catalysts). The catalyst typically lowers the activation barrier, increases the reaction rate, and can influence selectivity and yields without altering the final thermodynamic equilibrium.

Common examples include hydrogenation of organic compounds using metal catalysts, acid- or base-catalyzed transformations, and enzyme-catalyzed biochemical reactions. Industrial applications are broad, encompassing chemical synthesis, petrochemistry, and environmental processes such as catalytic converters in vehicles.

In literature and technical writing, the term catalisadas appears when describing experiments, processes, or pathways where a catalyst has been employed to achieve faster kinetics. It is contrasted with catalizadas (or non-catalyzed) cases to highlight the role of the catalyst in shaping the reaction rate and outcome.
