Figure 6.

(a) CO-induced stress (Δf) measured during CO stripping as a function of CO surface coverage. The coverage was determined from CO stripping charge using eq 5 while the stripping stress (Δf) was taken from Figure 5. (b) Coverage vs potential plot for the CO-saturated electrolyte calculated from the Figure 5 stress values from potentiostatic pulses, using the linear relationship in panel (a). The CO-free coverage was taken from panel (a). The solid lines are only a guide for the eye.
