Consider an Elementary Reaction $M _ { s o l } ^ { 3 + }+ 3 e ^ { - } \underset { k _ { - 1 } } { \stackrel { k _ { 1 } } { \rightleftarrows } } M$

Consider an elementary reaction $M _ { s o l } ^ { 3 + }+ 3 e ^ { - } \underset { k _ { - 1 } } { \stackrel { k _ { 1 } } { \rightleftarrows } } M$



where M is a metal and
$$M _ { s o l } ^ { 3 + }$$
is metal ion in solution. F denotes faraday constant. The net faradaic current density due to metal deposition is given by

A) $$F k _ { 1 } \left[ M _ { s o l } ^ { 3 + } \right]$$
B) $$F \left\{ k _ { 1 } \left[ M _ { s a l } ^ { 3 + } \right] - k _ { - 1 } \right\}$$
C) $$3 F \left( k _ { 1 } \left[ M _ { s o l } ^ { 3 + } \right] + k _ { - 1 } \right)$$
D) $$3 F \left\{ k _ { 1 } \left[ M _ { s a l } ^ { 3 + } \right] - k _ { - 1 } \right\}$$
