Consider the following reaction $$A \underset { k _ { 2 } } { \stackrel { k _ { 1} } { \rightleftarrows } }B + e ^ { - }$$

. The concentration of A and B in bulk solution are equal. When a positive dc bias is applied (vs. OCP), under steady-state conditions, on the surface,

Quizplus · Accepted Answer

When a positive dc bias is applied, the reaction is driven towards the production of B and e^-. This means the concentration of B at the surface (C_B) will be greater than the concentration of A (C_A) under steady-state conditions, as the applied potential favors the forward reaction.
