Q10 of 30 Page 1

Determine the values of equilibrium constant (Kc) and ΔG° and for the following reaction:

Ni(s) + 2Ag+(s) → Ni2+ (aq) + 2Ag (s), E0= 1.05 V


(1 F = 96500 C/mol)


Here, n=2


So, ΔG° = -nFE0


= - 2 × 96500 × 1.05


= - 202650 Jmol-1 = -202.65 kJ mol-1


log Kc =


=


log Kc = 35.533


Kc = 3.412 × 1035
