At 600C, the flux of Carbon through a 2.00 mm thick sheet of steel is 7.86 x 10-6 kg/(m2.s). If the activation energy for carbon diffusion in steel is 120 kJ/mole, calculate the Carbon flux at 900C, assuming that the concentration gradient is the same as that at 600C. 0.00054 kg/(m2.s) 0.02 kg/(m2.s) 0.319 kg/(m2.s) O 0.000042 kg/(m.s)
