2. For the oxidation of Pb, U, and Al with 1 mol O2 (g) at 1000°C and 1500°C, what are the
following values. Please draw lines on the accompanying Ellingham diagram (Figure 1) to
clearly show your work. You may use more than one diagram (i.e., cut and paste this diagram).
a) $\Delta G_f$
b) $P_{O_2}$
c) CO/CO$_2$ ratio
d) H$_2$/H$_2$O ratio
