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+]= 0.173 M , [Co2+]= 0.433 M , and [Cl−]= 0.306 M , and the pressure of Cl2 is PCl2= 9.00 atm ?

Explanation:

The given data is as follows.

      = 0.483,     = 0.173 M,

      = 0.433 M,     = 0.306 M,

      = 9.0 atm

According to the ideal gas equation, PV = nRT

or,             P =    

Also, we know that

                Density =

So,         P = MRT

and,          M =

                    =

                    =

                    = 0.368 mol/L

Now, we will calculate the cell potential as follows.

          E =

             =

             =

             =

             =  0.483 - 0.0185

             = 0.4645 V

Thus, we can conclude that the cell potential of given cell at is 0.4645 V.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
