Question:

Zinc oxide (ZnO) ceramics are used in a variety of applications, such as surge protection devices. The diffusion of oxygen in single crystals of ZnO was studied by Tomlins and co-workers. These data are shown in the table here.

Using these data, calculate the activation energy for the diffusion of oxygen in ZnO. What is the value of D0 in cm2/s?
