Question:
The steady-state diffusion flux through a metal plate is 7.8 × 10-8 kg/m2.s at a temperature of 1200°C (1473 K) and when the concentration gradient is -500 kg/m4. Calculate the diffusion flux at 1000°C (1273 K) for the same concentration gradient and assuming an activation energy for diffusion of 145,000 J/mol?
