Which of the following is/are correct regarding resistance polarization?(a) Activation energy at the interface is the controlling factor(b) The resistance of transition between electrodes and electrolytes(c) Diffusion of ions in the bulk solution is the controlling factor(d) The resistance of reacting ions for diffusion is the controlling factorThe question was asked in examination.This interesting question is from Modern Theory Principles in portion Modern Theory Principles of Corrosion Engineering

Answer» RIGHT choice is (b) The RESISTANCE of TRANSITION between electrodes and electrolytes

The best explanation: Resistance polarization is the type of polarization in which there is a resistance of transition between electrodes and electrolytes. But this polarization has a negligible effect on corrosion kinetics.
