Question

What is the activation energy of an electrochemical reaction involving the oxidation of copper on a platinum electrode, if the reaction rate constant at 25°C is 2.5 x 10^-4 mol L^-1 s^-1 and the activation energy for the reaction is 64 kJ/mol?

Answer 1

The activation energy  Ea  for the reaction is already given as 64 kJ/mol. Therefore, there is no need to calculate it. The activation energy for the electrochemical reaction involving the oxidation of copper on a platinum electrode is 64 kJ/mol.
