For the reaction 2Co3+(aq)+2Cl−(aq)→2Co2+(aq)+Cl2(g) . E∘=0.483 V2Co3+(aq)+2Cl−(aq)→2Co2+(aq)+Cl2(g ). E∘=0.483 V what is the cell potential at 25 ∘C∘C if the concentrations are [Co3+]=[Co3+]= 0.324 MM , [Co2+]=[Co2+]= 0.158 MM , and [Cl−]=[Cl−]= 0.384 MM , and the pressure of Cl2Cl2 is PCl2=PCl2= 5.80 atmatm ?

Explanation:

We must use the Nernst equation

The equation for the cell reaction is is

2Cl⁻(0.384 mol·L⁻¹) + 2Co³⁺(0.324 mol·L⁻¹) ⇌ Cl₂(5.80 atm) + 2Co²⁺(0.158 mol/L)

Data:

E° = 0.483 V

R = 8.314 J·K⁻¹mol⁻¹

T = 25 °C

n = 2

F = 96 485 C/mol

Calculation:  

T = 25 + 273.15 = 298.15 K

i think so it’s will be b yes i believe its
