Question: The steady-state diffusion flux through a metal plate is 5.4 10-10 kg/m2-s at a temperature of 727C (1000 K) and when the concentration gradient

The steady-state diffusion flux through a metal plate is 5.4 × 10-10 kg/m2-s at a temperature of 727°C (1000 K) and when the concentration gradient is -350 kg/m4. Calculate the diffusion flux at 1027°C (1300 K) for the same concentration gradient and assuming an activation energy for diffusion of 125,000 J/mol.
