Consider the Reaction -In the Same Reaction, the Faradaic Current Is Given by s

Consider the reaction $$\begin{array} { l } P _ { s o l }\underset { k _ { - 1 } } { \stackrel { k _ { 1 } } { \rightleftarrows } }Q _ { - s o l } + e ^ { - } \\A _ { s ol } ^ { - } \underset { k _ { - 2 } } { \stackrel { k _ { 2 } } { \rightleftarrows } } A _ { a d s } + e ^ { - } \\\end{array}$$

-In the same reaction, the faradaic current is given by

A) $$i _ { F } = F \left\{ k _ { 1 } \left[ P _ { s o l } \right] ( 1 - \theta ) - k _ { - 1 } \left[ Q _ { s o l } \right] ( 1 - \theta ) + k _ { 2 } \left[ A _ { s o l } ^ { - } \right] ( 1 - \theta ) - k _ { - 2 } \theta \right\}$$
B) $$i _ { F } = F \left\{ k _ { 1 } \left[ P _ { s o l } \right] ( 1 - \theta ) - k _ { - 1 } \left[ Q _ { s o l } \right] \theta + k _ { 2 } \left[ A _ { s ol } ^ { - } \right] ( 1 - \theta ) - k _ { - 2 } \theta \right\}$$
C) $$i _ { F } = F \left\{ k _ { 1 } \left[ P _ { \text {sol } } \right] ( 1 - \theta ) - k _ { - 1 } \left[ Q _ { s o l } \right] ( 1 - \theta ) + k _ { 2 } \left[ A _ { s o l } ^ { - } \right] - k _ { - 2 } \theta \right\}$$
D) $$i _ { F } = F \left\{ k _ { 2 } \left[ A _ { s a l } ^ { - } \right] ( 1 - \theta ) - k _ { - 2 } \theta \right\}$$
