Consider the decomposition of a metal oxide to its elements, where M represents a generic metal.

M203(s)---> 2M(s) + 3/2 O2(g)

info given for Gf(kJ/mol):
M203= -6.70
M(s)=0
O2(g)= 0

what is the standard change in Gibbs energy for rxn as written in forward direction? (kJ/mol)
What is the equilibrium constant (K) of this rxn, as written in forward direction at 298K?

What is the equilibrium pressure of O2(g) over M(s) at 298K? (atm
