    8. Calculate \(\Delta{G}^o\) for Cu+2/Cu and Mn+2/Mn half-cells. Is this reaction spontaneous?

    Eo = 1.52 V;

    \(\Delta{G}^o = -293,360 J\)

    or

    \[- 293.4 \, kJ\]

    Yes, this reaction is spontaneous as written.


    5. Calculate \(\Delta{G}\) for Ni+2/Ni and Fe+2/Fe half-cells if the [Ni+2] = 0.25 M and the [Fe+2] = 0.50 M.

    Eo = 0.19 V; E = 0.181 V; DG = - 34956 J or - 35.0 kJ

    6. Determine the \(\Delta{G}\) for the Al+3/Al and Ni+2/Ni half-cells.if the [Al+3] = 0.50 M and the [Ni+2] = 0.25 M.

    Eo = 1.41 V; E = 1.398 V; \(\Delta{G}\) = - 809442 J or - 809.4 kJ
