Question: A thin layer of graphite ( C ) is plated onto a thick plate of iron and the couple is held at 1 , 2

A thin layer of graphite (C) is plated onto a thick plate of iron and the couple is held at 1,227 degrees C for some amount of time. If the approximate depth of penetration at which a there is a 30% concentration of C in the thick plate is 110m, find the time in seconds The diffusion constants are D0=8E-6m2s and Qd=131kJmol.
