The rate equationQt/Qinfin;= 1 minus;eminus;btn, whereQt/Qinfin;is the fractional yield of an interface reaction at timet, was shown to be formally analogous to the Weibull distribution functions. Further correlation between the Weibull and the normal distributions did allow for a direct statistical interpretation of surface processes. Rates are thus defined by the well known parameters mgr; and sgr;. Geometrically incompatible processes were standardized on the basis of the exponentnand the shape parameter bgr; of the Weibull distribution. For 3n4, processes obeyed the normal distribution, and forn0.7, they obeyed the log normal distribution. By using the linearized probability plots, ambiguities imposed by the multiple logarithming of the above rate equation are avoided.
