What is the Relationship Between Catalyst Concentration and Turnover Frequency (TOF)?
_Turnover Frequency (TOF)_ is a measure of the catalytic activity, defined as the number of times a catalytic site converts a reactant molecule to a product per unit time. The relationship between catalyst concentration and TOF is complex. While increasing catalyst concentration generally increases the overall reaction rate, TOF can vary depending on the availability of active sites and the efficiency of the catalyst.
In some cases, increasing catalyst concentration may lead to lower TOF if the additional catalyst results in fewer reactant molecules per active site, thus reducing the efficiency of each individual site.
