Question

Which of the following is/are the limitations of Tafel extrapolation?

(a) For reasonable accuracy, the Tafel region must be extended

(b) It can be applied to systems containing one reduction process only

(c) Much interference from concentration polarization

(d) It can be applied to systems containing one reduction process, for reasonable accuracy the Tafel region must be extended and there will be much interference from concentration polarization

This question was addressed to me in my homework.

Query is from Modern Theory Applications topic in division Modern Theory Applications of Corrosion Engineering

Answer 1

Correct choice is (d) It can be applied to systems containing one reduction process, for reasonable accuracy the Tafel region must be extended and there will be much interference from concentration polarization

Easy explanation: Limitations of Tafel extrapolation are:

For reasonable accuracy, the Tafel region must be extended

It can be applied to systems containing one reduction process only

Much interference from concentration polarization.
