Preferred Label : kinetic activity factor;
IUPAC definition : A factor involving activity coefficients that appears as a multiplier in the rate
equation. For a bimolecular reaction the factor is \[\frac{y_{{A}}\ y_{{B}}}{y_{\ddagger}}\]
where y A, y B and y ‡ are the activity coefficients for the reactants A and B and
the activated complex, respectively. For a unimolecular reaction the factor is \[\frac{y_{{A}}}{y_{\ddagger}}\]
and for a trimolecular reaction it is \[\frac{y_{{A}}\ y_{{B}}\ y_{{C}}}{y_{\ddagger}}\];
