Question: The steady - state diffusion flux through a metal plate is 7 . 8 1 0 - 8 k g m 2 - s at

The steady-state diffusion flux through a metal plate is 7.810-8kgm2-s at temperature of 1200C and when the concentration gradient is -500kgm4. Calculate the diffusion flux at 1000C for the same concentration gradient and assuming an activation energy for diffusion of 145000Jmol.
