Selectivity refers to the ability of a catalyst to favor the formation of a particular product over others. Reaction control can enhance selectivity by:
1. Tuning Reaction Conditions: Optimizing temperature, pressure, and concentration can favor the desired reaction pathway.
2. Using Specific Catalysts: Selecting catalysts that are designed to stabilize specific transition states or intermediates can direct the reaction towards the desired product.
3. Incorporating Additives: Additives can act as promoters or inhibitors to enhance the selectivity of the catalyst.
