Considere la semireaccin: Zn 2+ (aq) + 2 e - Zn(s), E o = -0.76 V
Cules son los potenciales de reduccin, E o , de las siguientes semirreacciones: A, B y C?
A: 2Zn 2+ (aq) + 4 e - 2Zn(s)
B: 1/2Zn(s) 1/2Zn 2+ (aq) + e -
C: Zn(s) Zn 2+ (aq) + 2 e -
Seleccione uno:
a. A : Eo = 0,76 V; B: Eo = -0,76 V; C: E o = 0,76 V
b. A: Eo = -1,52 V; B: Eo = -0,38 V; C: E o = 0,76 V
C. A: Eo = -1,52 V; B: Eo = 0,38 V; C: E o = 0,76 V
d. A: Eo = -0,76 V; B: Eo = 0,76 V; C: E o = 0,76 V
mi. A: Eo = -0,76 V; B: Eo = -0,76 V; C: E o = 0,76 V
