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+

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
