Such grave errors may be avoided if a more rigorous approach to kinetic modeling of this reaction system is taken. A best practice is to separate attempts to model the symmetry-breaking process, which can be sensitive to undetectable and uncontrollable influences, from modeling of the elementary steps involving catalyst turnover, which can monitored under controlled conditions through accurate measurements of the concentration of product added to the reaction. Both the monomer-dimer equilibria and the product formation rates may then be assessed by deterministic modeling of multiple data sets of controlled reaction conditions and then be validated by using the model parameters to predict the results of further sets of conditions. As was shown in Figure , the accuracy of the temporal prediction of ee from the parameters of the Blackmond/Brown dimer-active kinetic model lends strong support to the stochastic dimer (or tetramer)-active model. Once validated for well-defined conditions, such a kinetic model may be used in studies aimed at understanding the symmetry breaking process.
