For the reaction 2Co3+(aq)+2Cl−(aq)→2Co2+(aq)+Cl2(g). ?

E∘=0.483 V

what is the cell potential at 25 ∘C if the concentrations are [Co3+]= 0.287 M , [Co2+]= 0.779 M , and [Cl−]= 0.562 M , and the pressure of Cl2 is PCl2= 5.40 atm ?

    2Co³⁺(aq) + 2Cl⁻(aq) → 2Co²⁺(aq) + Cl₂(g)…… E° = 0.483 V

    2 mol of e⁻ are transferred when 2 mol of Co³⁺ is reduced to 2 mol of Co²⁺, i.e n = 2

    Temperature, T = (273 + 25) K = 298 K
