Consider the Reaction The Kinetic Parameters Are Given by K10 = 10-5 cm

Question 11

Short Answer

Consider the reaction Psak1Qsa+eAsilk2k2Aαij+e\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 Γ\varGamma = 10-8 mol cm-2. Solution species concentrations are given by [Psol] = [Qsol] =[
AsolA _ { s o l } ^ { - } ] = 100 mM.
-At the same potential (Edc = 0.25 V vs. OCP), the total Faradaic current is given by,
iF-dc = ______________ mA cm-2
