Question

(1) Calculate equilibrium constant at 25°C for the
cell Ni| Ni2+ (C) || Ag+ (C2) | Ag

Answer 1

Answer:

simple solution

Explanation:

first calculate the standard electrode potential of cell by given equation.

then apply the formula for equilibrium constant

E°cell= 2.303RT/nF * logKc  {E°cell here is 0.80-(-0.25) = 1.05}

simplifying the 2.303RT/nF so we get 0.059/2

1.05=0.059logKc/2

1.05*2/0.059=logKc

approximately logKc=35.593

so Kc = antilog(35.593)  {find the antillog}
