Question

The equilibrium constant, Kc for the reaction Cu(s) + 2Ag+(aq) leftharpoons Cu2+(aq) + 2Ag(s) ; E°cell = 0.46 V is (A) antilog 15.6 (B) antilog 2.5 (C) antilog 1.5 (D) antilog 12.2

Tardigrade Admin · Accepted Answer

Ecell° = (0.0591/n) log kc 0.46 = (0.0591/2) log Kc (0.46 × 2/0.0591) = log Kc : : ⇒ : log Kc = 15.56 ∴ : Kc = antilog 15.6

Q. The equilibrium constant, $K_{c}$ for the reaction
$C u_{(s)} + 2 A g_{(a q)}^{+} ⇌ C u_{(a q)}^{2 +} + 2 A g_{(s)}; E_{ce ll}^{\circ} = 0.46 V$ is

antilog 15.6

antilog 2.5

antilog 1.5

antilog 12.2

$E_{ce ll}^{\circ} = \frac{0.0591}{n} lo g k_{c}$
$0.46 = \frac{0.0591}{2} lo g K_{c}$
$\frac{0.46 \times 2}{0.0591} = lo g Kc \Rightarrow lo g K_{c} = 15.56$
$∴ K_{c} =$ antilog $15.6$
