Consider the decomposition of a metal oxide to its elements, where M represents a generic metal. M2O(s)↽−−⇀ 2M(s)+1/2O2(g) What is the standard change in Gibbs energy for the reaction, as written, in the forward direction? Δ????∘rxn= 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?
