During Class Invention Activity
1. Write a balanced chemical equation that describes the reaction between G and B in the BCE for today’s class. 
2. Based on your observations from the BCE record the results of all of the possible collisions enumerated in the table below.
 
  
    
      | Collision | Particle 1
        
       | Particle 2
        
       | Result of collision | 
    
      | 1. | G | B | No Change | 
    
      | 2. | G | G |   | 
    
      | 3. | B | B |   | 
    
      | 4. | G2 | G2 |   | 
    
      | 5. | G2 | B |   | 
    
      | 6. | G2 | G |   | 
    
      | 7. | GB | B |   | 
    
      | 8. | GB | G |   | 
    
      | 9. | GB | G2 |   | 
    
      | 10. | GB | GB |   | 
  
 
3. Based on results from Question 2, what two collisions (called elementary steps) are required to convert reactants to products.
4. Based on results from Question 2, propose a step-by-step process (a mechanism) that converts reactants to products.
5. Describe the role of G2 in the overall mechanism of the reaction between G and B.
6. A possible mechanism for the reaction is the one step collision between  three reacting particles: 
  G + G + B ---> G2B. 
Is this a likely mechanism for this reaction? Why or why not. 
7. Suggest a possible mechanism for the following reaction: 
NO2 + CO ---> NO + CO2
