Which of the following is/are true regarding parabolic oxidation rate law?(a) It was proposed by C. Wagner(b) It states that square of weight loss is directly proportional to the time of exposure(c) It was proposed by C. Wagner which states that square of weight loss is directly proportional to the time of exposure and it resembles non-steady-state diffusion-controlled reactions(d) It resembles non-steady-state diffusion-controlled reactionsThe question was asked in an online interview.The query is from High-Temperature Corrosion in division High Temperature Corrosion of Corrosion Engineering

Answer»

Right choice is (c) It was PROPOSED by C. Wagner which states that SQUARE of weight loss is DIRECTLY proportional to the time of EXPOSURE and it resembles non-steady-state diffusion-controlled reactions

The explanation is: True statements regarding parabolic oxidation rate LAW:

It was proposed by C. Wagner

It states that square of weight loss is directly proportional to the time of exposure

It resembles non-steady-state diffusion-controlled reactions.
