Question

a metal M can be removed from molten lead but selective oxidation at 1173K. Assuming that M forms an ideal solution with lead , determine the limiting concentration to which M can be removed from lead.
use the following data
1) 2PbO + O2 = 2PbO. G°= -200832 J
2) 2M + 3/2O2 = M2O3 . G°= -334720 J
atomic mass of M = 122g/mol
atomic mass of M = 207g/mol
