Corrosion of metals in aerated aqueous environments involves the following cathodic reaction: (i) O2(aq) + 2H2O(l) +4e- →40H(aq) E° = +0.401 V Calculate the equilibrium constant for the above cathodic reaction at equilibrium under standard conditions at 298 K. (ii) Write which species will predominate in the system if the above cathodic reaction is maintained at equilibrium under standard conditions at 298 K. (iii) Using standard cell notation, write out the electrochemical cell for the chemical equilibrium that describes the corrosion process of a divalent metal (M) in an aerated aqueous environment: 2Me(s) + 2H2O(1)+ O2(aq) → 2M²+(aq) + 40H(aq) Corrosion of metals in aerated aqueous environments involves the following cathodic reaction: (i) O2(aq) + 2H2O(l) +4e- →40H(aq) E° = +0.401 V Calculate the equilibrium constant for the above cathodic reaction at equilibrium under standard conditions at 298 K.
