Consider the Reaction -In the Same Mechanism, the Charge Transfer Resistance (R_t) Is

Consider the reaction $$\begin{array} { l } M \stackrel { k _ { 1 } } { \longrightarrow } M _ { a ds } ^ { + } + e ^ { - } \\M + M _ { a d s } ^ { + } \stackrel { k _ { 2 } } { \longrightarrow } M _ { a d s } ^ { + } + M _ { s o l } ^ { + } + e ^ { - } \\M _ { a d s } ^ { + } \stackrel { k _ { s } } { \longrightarrow } M _ { s o l } ^ { + }\end{array}$$
-In the same mechanism, the charge transfer resistance (R_t) is given by

A) $$\left( R _ { t } \right) ^ { - 1 } = F \left\{ b _ { 1 } k _ { 1 dc } \left( 1 - \theta _ { ss } \right) - b _ { 2 } k _ { 2 dc } \left( 1 - \theta _ { s s } \right) \theta _ { s s } \right\}$$
B) $$\left( R _ { t } \right) ^ { - 1 } = F \left\{ b _ { 1 } k _ { 1 dc} \left( 1 - \theta _ { ss } \right) + b _ { 2 } k _ { 2dc } \left( 1 - \theta _ { s s } \right) \theta _ { s s } \right\}$$
C) $$\left( R _ { t } \right) ^ { - 1 } = F \left\{ b _ { 1 } k _ { 1 d c } \left( 1 - \theta _ { s s } \right) + b _ { 2 } k _ { 2 dc } \theta _ { s s } \right\}$$
D) $$\left( R _ { t } \right) ^ { - 1 } = F \left( b _ { 1 } k _ { 1 d c } \left( 1 - \theta _ { s s } \right) - b _ { 2 } k _ { 2 dc } \theta _ { s s } \right\}$$
