Calcular el potencial de celda E a 25C para la reaccin 2 Al( s ) + 3 Fe 2+ ( aq ) 2 Al 3+

Calcular el potencial de celda E a 25C para la reaccin

2 Al( s ) + 3 Fe 2+ ( aq ) 2 Al 3+ ( aq ) + 3 Fe( s )

dado que [Fe 2+ ] = 0.020 M, [Al 3+ ] = 0.10 M, y el potencial de reduccin estndar es -1.66 V para Al 3+ /Al y -0.45 V para Fe 2+ /Fe. [Ecuacin dada: E = E o -(0.0592/n) log(Q) ]

+1,20 V

+1,03 V

+1,15 V

+1,18 V
