Question

Which of the following is/are the hypothesis of mixed potential theory?

(a) Any electrochemical reaction can be divided into two or more partial reactions

(b) No net accumulation of electric charge during the reaction

(c) Any electrochemical reaction can be divided into two or more partial reactions and no net accumulation of electric charge during the reaction

(d) Electrochemical reactions can’t be divided into partial reactions

The question was asked during a job interview.

My question is taken from Modern Theory Principles in portion Modern Theory Principles of Corrosion Engineering

Answer 1

Correct choice is (c) Any electrochemical reaction can be divided into two or more partial reactions and no net accumulation of electric charge during the reaction

The best I can explain: Hypothesis of mixed potential theory:

i. Any electrochemical reactions can be divided into two or more partial reactions

ii. No net accumulation of electric charge during the reaction.
