Consider the decomposition of a metal oxide to its elements, where M represents a generic metal.
M2O3(s) → 2M(s) + 3/2 O2(g)
Informaton given for G f(kJ/mol):
M2O3 = -6.70
M(s) = 0
O2(g) = 0
a. What is the standard change in Gibbs energy for rxn as written in forward direction?
b. What is the equilibrium constant (K) of this rxn, as written in forward direction at 298K?
c. What is the equilibrium pressure of O 2(g) over M(s) at 298K?
