H ₂(g)+2 AgCl (s) 2 Ag (s)+2 HCl (a q)E_ cell ^ at 25^ C for the cell is 0.22 ~V . The equilibrium constant at 25^ C is

Step-by-step solution

For given reaction, E_ cell ^ at 25^ C =0.22 ~V At equilibrium, aligned E_ cell ^ &= 0.059 n K_ C K_ C &= E_ cell ^ n 0.059 = 0.22 2 0.059 =7.45 K_ C &= antilog 7.45 &=2.8 10⁷ aligned
