Give me some responses to the questions below and I'll give you some extra credit.


Laboratory Section:

1. Based on our discussion in class on Monday, September 24, 2001 in order for a reaction to occur the reactant atoms/molecules/particles must collide. Describe other factors that are necessary before a reaction can occur when reactant particles collide.

2. When considering collisions between molecules which of the following do you think is the most probable kind of collision;

between two molecules
between three molecules
between four molecules
between more than four molecules

Support your choice with a brief explanation.

3. Speed of a chemical reaction is an important issue for our study of chemical kinetics. What does 'speed' of a chemical reaction mean to you?

4. How would we experimentally measure the speed of a chemical reaction?

5. Consider the following reaction;

NO2(g) + CO(g) ---> NO(g) + CO2(g)

Briefly explain what you think will happen for the reactants to be converted to products.

6. Are all collisions between the reactants in the equation described in Question 5 above, effective? Yes or No.

7. In terms of collisions between the reactants in the Question 5 above describe at least two different ineffective collision.

8. Is there anything about the reaction or the questions that you feel you do not understand? List your concerns/questions.
