Question

Part A

Use the table of standard reduction potentials given above to calculate the equilibrium constant at standard temperature (25 ?C) for the following reaction:

Fe(s)+Ni2+(aq)?Fe2+(aq)+Ni(s)

Express your answer numerically.

Calculate the standard cell potential (E?) for the reaction

X(s)+Y+(aq)?X+(aq)+Y(s)

if K = 1.68

Reduction half-reaction E? (V) Ag+(aq)+e??Ag(s) 0.80 Cu2+(aq)+2e??Cu(s) 0.34 Sn4+(aq)+4e??Sn(s) 0.15 2H+(aq)+2e??H2(g) 0 Ni2+(aq)+2e??Ni(s) ?0.26 Fe2+(aq)+2e??Fe(s) ?0.45 Zn2+(aq)+2e??Zn(s) ?0.76 Al3+(aq)+3e??Al(s) ?1.66 Mg2+(aq)+2e??Mg(s) ?2.37
