The equilibrium cell potential of the galvanic cell
Pt | H2 (g, f =1 bar) HCl (aq, 0.500mol kg-1) | Cl2 (g, f =1 bar) | Pt
is found to be Ecell, eq = 1.410V at 298.15K. The standard cell potential is E°cell, eq = 1.360V.
(a) Write the cell reaction and calculate its thermodynamic equilibrium constant at 298.15K.
(b) Use the cell measurement to calculate the mean ionic activity coef?cient of aqueous HCl at 298.15K and a molality of 0.500mol kg-1.
