Given , Cu^(2+) + e^(-) to Cu^(+) E^(@) = 0.15 " volt " , Cu^(+) + e^- to Cu E^(@) = 0.5 volt Calculate potential for Cu^(2+) + 2e^(-) to Cu

Answer»

`0.65 V `
`0.325 V `
`0.45 V `
`1.2 V `

SOLUTION :`(3)= (1) +(2),DeltaG_(3)^(0) = DeltaG_(1)^(0)+ DeltaG_2^(0) , 2E_(3)^(0) = (1E_(1)^(0) + 1E_(2)^(0))=(0.15 + 0.5)/(2) = (0.652)/(2),E_3^(0) = 0.325 V `
