Answer:
844°C
Explanation:
The problem can be easily solve by using Fick's law and the Diffusivity or diffusion coefficient.
We know that Fick's law is given by,
Where is the concentration of gradient
D is the diffusivity coefficient
and J is the flux of atoms.
In the other hand we have, that
Where is the proportionality constant,
R is the gas constant, T the temperature and is the activation energy.
Replacing the value of diffusivity coefficient in Fick's law we have,
Rearrange the equation to get the value of temperature,
We have all the values in our equation.
Substituting,
