the reaction. The Collision Theory Gizmo allows you to experiment with several factors that affect the rate at which reactants are transformed into products in a chemical reaction. You will need blue, green, and orange markers or colored pencils for the first part of this activity. 1. Look at the key at the bottom of the SIMULATION pane.
1. Explain collision theory. 2. What are the two things that must take place in order for a reaction to take place between molecules or atom? 3. Explain why all reactions have activation energy, using your knowledge of collision theory. 4. Describe how the activation energy of a reaction affects the overall rate of the chemical reaction. 5.

(There will now Reactant concentration to 2 mol/L. Use the Gizmo to measure the half-life of tbe 20 reactant molecules left at the half-life.) Then,he calculate the mean half-life for each setting. Trial Minimum surface area Maximum surface area 1 9:34 2: 2 9:48 1: Mean half-life 9m 41s 1m 46s 4. Analyze: What do your results indicate?

1) Using collision theory, give two reasons why reactions occur more rapidly at a higher temperature. (2 marks) There is a greater fraction of collisions with sufficient energy. There are more frequent collisions because the particles are moving faster. 2) A reaction does not always occur when two reactant particles collide. Give two reasons why.
Collision Theory Worksheet Answers. Explain why all reactions have an activation energy, using your knowledge of collision theory. All reactions have an activation energy because energy is required to make the reactants combine in a way that will cause the reaction.
