copper oxidises in air at 1000c with parabolic kinetics, forming a surface film of cu2o. the parabolic rate constant at this temperature, kp, is 2.1 106 kg2 /m4 s. what is the mass gain per unit area of the copper surface after 1 h? how thick will the oxide be after this time? (the atomic weight of copper is 63.5 kg/kmol, that of oxygen is 16 kg/kmol, and the density of cu2o is 6000 kg/m3 .)
