1. Actual Yield vs. Theoretical Yield: The actual yield is the amount of product obtained from the reaction, while the theoretical yield is the maximum amount of product that could be formed based on stoichiometry. The reaction yield is often expressed as a percentage of the theoretical yield.
2. Turnover Number (TON) and Turnover Frequency (TOF): These metrics are used to evaluate the performance of a catalyst. TON is the total number of reactant molecules converted per catalyst site, and TOF is the rate at which these conversions occur.
