Before revision:  We explore how the idea of Gale duality can be used to learn about the steady states of fewnomial networks. In particular, we give precise conditions in terms of the reaction rate constants for the number and stability of the steady states of families of reaction networks with one non-flow reaction.
After revision:  Using this Gale duality we give precise conditions in terms of the reaction rate constants for the number and stability of the steady states of families of reaction networks with one non-flow reaction.
