Consider oxidation of a metal plate (half-thickness, x_0= 0.02m). After 800hours = 2.88E6 seconds at 900 C, the oxide layer thickness is 0.0005m. Assume the diffusion controlled quasi- steady state model.

a) calculate the (instantaneous) oxidation rate (m/s and mm/year) at t = 800hours. (t from the onset of oxidation)

b) calculate the time required for the oxide layer to grow from 0 m thick at t=0 to 0.002m thick.
