In this article, the reason that the iron powder reacts with chlorine to produce iron(III) trichloride under appropriate conditions is explained according to fundamentals of chemical thermodynamics. And the calculation result from Gibbs-Helmholtz equation reveals that the iron powder can react with chlorine to produce iron(II) dichloride at the temperature higher than 626 K. The calculation can not only reflect the guidance of chemical thermodynamics on inorganic synthesis, but also enhance
