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+]= 0.859 M , [Co2+]= 0.413 M , and [Cl−]= 0.439 M , and the pressure of Cl2 is PCl2= 5.10 atm ?

0.46V

Explanation:

This problem requires us to find the cell potential under conditions other than standard conditions. The cell potential for various systems under standard conditions are easily obtained from reduction potential tables. However, under nonstandard conditions, the cell potential is obtained from Nernst equation provided the relative concentration of individual species and the standard cell potential is supplied.

Nernst equation was applied in the detailed solution attached

quartz

explanation:

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
