Consider the decomposition of a metal oxide to its elements, where M represents a generic metal.
M2O3(s) → 2M(s) + 3/2 O2(g)
Info given for Gf(kJ/mol):
a) What is the standard change in Gibbs energy for rxn as written in forward direction? (kJ/mol)
b) What is the equilibrium constant (K) of this rxn, as written in forward direction at 298K?
c) What is the equilibrium pressure of O2(g) over M(s) at 298K? (atm)
