The activation energy of a chemical reaction is kind of like that "hump" you have to get over to get yourself out of bed. Even energy-releasing (exergonic) reactions require some amount of energy input to get going, before they can proceed with their energy-releasing steps. Bismuth is being used to disperse silicon at 1100°C for 20 minutes (Bi). So total quantity of Bi in the sample D= Do exp (-E/kT). and linear is 2 × 1015 Bi atoms/cm², and the diffusion length is 1 m. Use approximation. a.) How much Bi is there in total in the sample? b) What is the activation energy worth?

Question
Transcribed Image Text:The activation energy of a chemical reaction is kind of like that "hump" you have to get over to
get yourself out of bed. Even energy-releasing (exergonic) reactions require some amount of
energy input to get going, before they can proceed with their energy-releasing steps. Bismuth is
being used to disperse silicon at 1100°C for 20 minutes (Bi). So total quantity of Bi in the sample
is 2 x 1015 Bi atoms/cm?, and the diffusion length is 1 m. Use D = Do exp ( – E,/kT). and linear
approximation.
a.) How much Bi is there in total in the sample?
b) What is the activation energy worth?
