At temperatures between 775(C (1048 K) and 1100(C (1373 K),

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).
