- The relationship between E⁰cell and K at 298K is E⁰cell = (0.0591/n) log₁₀(K), where n is the number of electrons transferred in the balanced redox reaction. - The given reaction is A(S) + 2B⁺ ⇌ A²⁺ + 2B. - The equilibrium constant K = 10¹².
For a cell reaction A(S) + 2B⁺ ⇌ A²⁺ + 2B the equilibrium constant is found to be 10¹². Then the E⁰cell value is
