For the reaction H2+2AgCl+(s)+2H3O++2Cl- at 250C. The slandered free energy of formation of AgCl (s), H2O(l), H3O+ and Cl- are -110,-237, -200-α, (-168+α)KJ/mol. Where α is not known. Calculate the cell voltage if this reaction is run at 250C and 0.8 atm in a cell in which [H3O+] and [Cl-] are 0.006M and 0.02M respectively
