Fig. 4

Corrected version of Fig. A.2 in Du et al. (2012). The ratios (κ1κ4)/(κ2κ3) and 2.5 × 108 gO/gCO are used in the text to explain the appearance of the spike-like feature in the evolution curves, where 2.5 × 108 is the ratio between two related reaction rates. The abundances of a few other species are plotted for reference (not to scale).
