Test Material

For the test tomorrow, make sure you know the following subjects:
Physics:
Electricity and Radioactivity.
Chemistry:
Rates and energy.
Biology:
Simple inheritance

Try the quizzes on the bitesize links above, and use the handouts that you were given last week to practice more exam type questions.
If you want more exam practice, try the AQA page for all the past papers for year 11. Obviously, some of these are topics we haven't covered yet but if you just do the ones that relate to what's listed on this post above, you should be ready for tomorrow.
Good luck, and let me know tomorrow morning if you have any questions!

Progress test revision

Today we're going to do a bit of summary revision stuff for the progress test tomorrow. Answer the following in your books:

1. What is collision theory?
2. What is the activation energy in a reaction? How does it change when you add a catalyst?
3. Give an example of an exothermic and an endothermic reaction:
4. Briefly describe the Haber process, and explain what it produces:
5. How would you get a higher yield from a reversible reaction which is exothermic going forward?
6. If the atomic number for He is 2, how many electrons would this atom contain?
7. What particles make up the nucleus?
8. Explain what fission and fusion are.
9. This diagram shows a Helium isotope emitting a beta particle. How could you write an equation to show this?                                                               
10. What are the three types of radiation?
11. Finally, try and finish this activity. What charges attract each other? What name would you give to the positive and negative particles?

Rates of reaction/energy

We're going to revise some of the rates of reaction stuff we've already covered in class, and keep looking at exo/endothermic reactions. Answer the following in your books:

1. What does a catalyst do? Give an example of a biological catalyst from this link:
2. Name the catalyst in this reaction and explain what it does:
3. Why are catalysts important in industrial processes?
4. Watch this animation, and explain how reaction rates can be measured:
5. What does the Haber process produce? What is this product used for?
6. Watch this video on the Haber process. What two things determine what temperature and pressure to carry out the reaction?                                            
7. What is a reversible reaction? What things can influence which way it goes?
8. What is the relationship between pressure and % yield of ammonia? What is the yield at 300 atmospheres?

HOMEWORK
You need to name two other catalysts and explain what reactions they are involved with. This is due on Friday.
