Preparation of chromium complexes such as [Cr(en)3](ClO4)3, the typical starting material is CrCl3 6H2O. When combined with excess ethylenediamine in an appropriate solvent, the reaction proceeds slowly, however the addition of a small, catalytic piece of Zn rapidly accelerates the reaction. Discuss this reaction in terms of the role Zn as a catalyst and the relative labilities of the oxidation state (or states) of chromium involved.
Dinitrogen tetroxide (N2O4) dissociates via the reaction: N2O4 (g) ? 2NO2 (g). 3.00 × 10-2 mol N2O4 (g) is introduced into a 1.000L flask. At equilibrium, 2.36 × 10-2 mol N2O4 (g) remains. What is the equilibrium constant for this reaction?
