Consider the decomposition of a metal oxide to its elements, where M represents a generic metal. M3O4(s) 3M(s) + 2O2(g) Substance delta G degree f (kJ/mol) M3O4 -9.50 M(s) 0 O2(g) 0 What is the standard change in Gibbs energy for the reaction, as written, in the forward direction? delta G degree rxn = Number ____________ kJ / mol What is the equilibrium constant of this reaction, as written, in the forward direction at 298 K? Number k = Number What is the equilibrium pressure of 02(9) over M(s) at 298 K? PO2 = Number __________ atm
