Multiple Choice

A) equilibrium constants for the equilibrium reactions that can be combined to make the new equilibrium
B) $\Delta$ $G _ { f } ^ { \circ }$ Values for the reactants and products of the new reaction)
C) $\Delta$ H_f and S° values for the reactants and products of the new reaction)
D) All of the above.
