By definition, "chemical spontaneity" corresponds to the SIGN of DeltaG_"rxn"^@.....DeltaG="Gibbs' Free energy...."

Explanation:

For A + B rightleftharpoonsC+D

DeltaG=-RTln{K_"eq"}

If DeltaG=0, then the reaction is at equilibrium; if DeltaG is positive, then the REACTANTS are favoured at equilibrium; if DeltaG is NEGATIVE, then the PRODUCTS are favoured at equilibrium, and the reaction is said to be "spontaneous", i.e. DeltaG<=0...........
