Consider the reaction $$\begin{array} { l } P _ { s a } \stackrel { k _ { 1 } } { \longrightarrow } Q _ { s a } + e ^ { - } \\A _ { s i l } ^ { - } \underset { k _ { - 2 } } { \stackrel { k _ { 2 } } { \rightleftarrows } } A _ { \alpha i j } + e ^ { - } \\\end{array}$$
The kinetic parameters are given by k₁₀ = 10^-5 cm s^-1, b₁ = 20 V^-1, k₂₀ = 10^-6 cm s^-1, b₂ = 20 V^-1, k_-20 =10^-6 mol cm^-2 s^-1 , b_-2 = -18 V^-1 and $\varGamma$ = 10^-8 mol cm^-2. Solution species concentrations are given by [P_sol] = [Q_sol] =[
$$A _ { s o l } ^ { - }$$ ] = 100 mM.
-The equation for fractional surface coverage of A_ads is given by

A) $$\frac { k _ { 2 \dot { dc } } } { k _ { 2 k \dot { dc } } + k _ { - 2 \dot { dc } } + k _ { 1 \dot { dc } } }$$
B) $$\frac { k _ { 2 dc } } { k _ { 2dc } + k _ { - 2 \dot {dc } } }$$
C) $\frac{k_{2 dc} C_{\mathcal{A}^-_{\mathrm{sol}}}}{k_{2 dc} C_{A^-_{sol}}+k_{-2 d c}+k_{1 d c} C_{P_{sol}}}$
