Concept explainers
(a)
Interpretation:
The units of Do and E should be identified.
Concept introduction:
Diffusivity is calculated as follows.
Where,
Do = the preexponential factor.
E = the activation energy for diffusion.
R = 1.987
(b)
Interpretation:
The plot for straight line on rectangular coordinates should be explained.
Concept introduction:
Diffusivity is calculated as follows.
Where,
Do = the preexponential factor.
E = the activation energy for diffusion.
R = 1.987
(c)
Interpretation:
Plot the data in rectangular coordinates and find the values for D0 and E from the resulting line.
Concept introduction:
Diffusivity is calculated as follows:
Where,
Do = the preexponential factor.
