The relationship between exponential decline (Figure. 4) and molecular weight of olefin intermediates, Mowry shale, 11 hours at 100°C. Alpha along the y axis is the exponent to the exponential curves given in the legend of Figure. 4. Olefin MW represents the molecular weights of C2 to C5 olefins, the intermediates in [Cn]. The red line is the regression curve: y = 2035*ln(x) - 6385; R2 = 0.99.
