Question: The steady-state diffusion flux through a metal plate is 5.4 ( 10 -10 kg/m 2 -s at a temperature of 727C (1000 K) and when

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.
