What is the equation for the equilibrium deposition potential?
What is the equation for the equilibrium deposition potential?
- $e_{eqm} = e_o - ln C Z F$
- $e_{eqm} = e_o imes ln C Z F$
- $e_{eqm} = e_o imes rac{ln C}{Z F}$
- $e_{eqm} = e_o + rac{ln C}{Z F}$ (correct)
What extra voltage should be added in cases where the equilibrium deposition potential is not sufficient to start the reaction?
What extra voltage should be added in cases where the equilibrium deposition potential is not sufficient to start the reaction?
- $e_{act} = e_{eqm} - \eta_{a}$
- $e_{act} = e_{eqm} \times \eta_{a}$
- $e_{act} = e_{eqm} + \eta_{a}$ (correct)
- $e_{act} = e_{eqm} \div \eta_{a}$
