Question
Cu+ + e- → Cu Eo = a1 volt
Cu+2 + 2e- → Cu Eo = a2 volt
then for Cu2+ + e- → Cu+, Eo will be :-
Cu+2 + 2e- → Cu Eo = a2 volt
then for Cu2+ + e- → Cu+, Eo will be :-
Options
A.a1 - 2a2
B.a2 - a1
C.a1 - a2
D.2a2 - a1
Solution
(1) Cu+ + e- → Cu; ᐃGo1
(2) Cu2+ + 2e- → Cu; ᐃGo2
Now on eqn. (2) - eqn (1)
Cu2+ + e- → Cu+; ᐃGo3 = ᐃGo2 - ᐃGo1
or - n3FEo3 = - n2FEo2 - (-n1FEo1)
-1 × Eo3 = - 2 × Eo2 + 1 × Eo1
Eo3 = 2a2 -a1
(2) Cu2+ + 2e- → Cu; ᐃGo2
Now on eqn. (2) - eqn (1)
Cu2+ + e- → Cu+; ᐃGo3 = ᐃGo2 - ᐃGo1
or - n3FEo3 = - n2FEo2 - (-n1FEo1)
-1 × Eo3 = - 2 × Eo2 + 1 × Eo1
Eo3 = 2a2 -a1
