If the standard electrode potential for a cell is 2 V at 300 K, the equilibrium constant (K) for the reaction

Zn(s) + Cu²⁺ (aq) $$\rightleftharpoons$$ Zn²⁺(aq) + Cu(s)

at 300 K is approximately,

(R = 8 JK^$$-$$1mol^$$-$$1, F = 96000 C mol^$$-$$1)

Homoleptic octahedral complexes of a metal ion 'M³⁺' with three monodenate ligands L₁, L₂ and L₃ adsorb wavelenths in the region of green, blue and red respectively. The increasing order of the ligands strength is :
