Sulfur dioxide and sulfate ion concentrations, measured in a suburban area near Budapest, and previously used in a general study of correlations among aerometric parameters (Mészáros, 1973), are used to derive estimates of activation energy and rate of sulfur dioxide-to-sulfate conversion. Two different analyses are made, one based upon purely meterological considerations, and the other on the grouping of data. The first yields an estimate of the half-life of sulfur dioxide of approx. 2 h, and the other of 10 h. The corresponding activation energies are respectively 23 and 9 kcal mole-1. Both treatments lead to statistically significant correlation coefficients. However, the scatter of data and the small number of points prevent a clear decision between the alternatives. It appears that the method is valid, but that far more data are needed before a decision can be made concerning the true values of the key kinetic constants.
