Transition Metals 3

Catalysts and Inorganic Compound Reactions

What are the two types of Catalyst? Heterogenous and Homogenous.
What is a Heterogenous Catalyst: A Catalyst which is in the a different phase to the reactants, usually a solid providing a surface for a reaction to occur.
What is a Homogenous Catalyst? A Catalyst which is in the same phase as the reactants. They form reactive intermediates before being regenerated.
Give 3 Examples of Heterogenous Catalysts in industrial processes: Iron in the Harbour Process. V2O5 (Vanadium Oxide) in the Contact process. Chromium Oxide (Cr2O3) in the production of Methanol via Synthesis Gas.
Explain the Contact Process and the role of its Catalyst: 2SO2 + O2 <---> 2SO3 V2O5 + SO2 --> SO3 + V2O4 2 V2O4 + O2 ---> 2 V2O5
What is the Catalyst for the Harbour Process: Fe
What is the Catalyst for the Contact Process: V2O5
What is the Catalyst for production of Methanol? Cr2O3
What are the 2+ ions which are covered in this unit: Fe2+, Cu2+ and Co+ (Iron (II), Copper (II) and Cobalt (II))
What are the 3+ ions covered in this unit: Fe3+, Cr3+ and Al3+ (Iron (III), Chromium (III) and Aluminium (III)).
Lewis Base: An electron Pair Donor
Lewis Acid: Electron Pair acceptor.
Which are stronger Acids, 2+ or 3+ ions: The 3+ ions are stronger because they draw charge density from lone pairs towards themselves more and this leaves H atoms more delta positive than in 2+ ions.
Give as basic Formula of a M2+ ion in solution: [M(H2O)6]2+
Give the basic formula of a M+ ion in solution: [M(H2O)6]3+
