The logarithm of the interface velocity is plotted vs the inverse temperature . Data based on our direct measurements of the propagation of the interface using optical movies of the visible opacity change are plotted as diamonds; data from similar measurements from Ref. 4 are plotted as rectangles; data obtained from the equation , where is the half-transformation time from Refs. 2 and 3, and is the effective propagation length (the same for all points and chosen to yield the best fit) are plotted as triangles. A change in shifts all triangles in the vertical direction by the the same value. Experimental data from Ref. 4 obtained using differential scanning calorimetry measurements are plotted as circles. Lines 1 are based on our Eq. (1) with three different preexponential factors, for the middle curve; a change in preexponential multiplier by a factor of 2.1 shifts the middle curve by 0.32 up and down. Line 2 is a fit suggested in Ref. 4.
