At temperatures between 775(C (1048 K) and 1100(C (1373 K),
At temperatures between 775(C (1048 K) and 1100(C (1373 K), the activation energy and preexponential for the diffusion coefficient of Fe2+ in FeO are 102,000 J/mol and 7.3 ( 10-8 m2/s, respectively. Compute the mobility for an Fe2+ ion at 1000(C (1273 K).
