Question

Which of the following subjects are important in understanding and controlling corrosion?

(a) Thermodynamics

(b) Electrochemistry

(c) Both Thermodynamics and Electrochemistry

(d) Material Characterization

This question was posed to me by my college director while I was bunking the class.

This is a very interesting question from Corrosion and its Classification in section Corrosion Principles of Corrosion Engineering

Answer 1

The correct answer is (c) Both Thermodynamics and Electrochemistry

Easiest explanation: Thermodynamic studies and calculations indicate the spontaneous direction of the reaction. The thermodynamic stability of corrosion product is relatively higher than reactant. Whereas the electrochemistry deals with electrode kinetics of the reaction.
