Problem

Two cells, K and L, each perform the reaction Ni(s) + Cu²⁺(aq) → Ni²⁺(aq) + Cu(s). Both operate at 298 K with

E^{\circ}=0.250\,\text{V}

and

n=2

. Cell K: [Ni²⁺] = 0.010 M, [Cu²⁺] = 1.0 M Cell L: [Ni²⁺] = 1.0 M, [Cu²⁺] = 0.010 M For one mole of electrons transferred, which cell can deliver more maximum electrical work to an external circuit? Support your answer in one sentence.
