In Figures 4a–c and 5a–d, the ,experimental data, are presented along with their exponential fitting curves. If eq 16 adequately represents the system, all fitted curves in Figure 5 a–d should be identical as each subfigure represents a consistent initial liquid height, i.e., the exponential constant in eq 16 would be equal for all cases if the gas phase was leaving fully equilibrated.
