Calculate the activation energy for the following electrochemical reaction: 2H₂O(l) → O₂(g) + 4H⁺(aq) + 4e⁻ if the half-cell potentials are: E°(O₂/H₂O) = 1.23 V E°(H⁺/H₂) = 0 V Assuming the reaction follows Arrhenius equation, where the rate constant k is related to the activation energy Ea, temperature T and pre-exponential factor A by: k = A exp(-Ea/RT) where R is the gas constant equal to 8.314 J/molK.
