In the table, weight gain-time data for the oxidation of copper at an elevated temperature are tabulated.
W (mg/cm2) Time (min)
0.316........................... 15
0.524........................... 50
0.725........................... 100
(a) Determine whether the oxidation kinetics obey a linear, parabolic, or logarithmic rate expression.
(b) Now compute W after a time of 450 min.
