Consider the decomposition of a metal oxide to its elements, where M represents a generic metal. AG® (kJ/mol) M20,(s) – 2M(6) +0,(E) Substance M203(s) M(s) 0 (g) -7.60 0 0 What is the standard change in Gibbs energy for the reaction, as written in the forward direction? AG = kJ/mol What is the equilibrium constant of this reaction, as written, in the forward direction at 298 K? What is the equilibrium pressure of O2(g) over M(s) at 298 K? Po,
