A couple of ?'s I just can't figure out.... 1. Reaction H2 + I2 <--->2HI, Keq = 017 @500K. Whatconcentration of I2 will be in the equilibrium w/H2=0.040M, HI =0.015M? I tried using the Keq = [C]c[D]d/[A]a[B]b &rearranged but don't even think that's the formula to use.... 2. Balance the following oxidation-reduction equations withsteps: a) P + HNO3+ H2O ---> H3PO4 + NO b) H2SO4 + HI ---> H2S + I2+ H2O c) Sb + HNO3 ---> Sb2O5 + NO + H20 Any help on all or some of these would beappreciated...assignment is now overdue!!
