Presentation Transcript

Rates of Reaction and Collision Theory : 

Rates of Reaction and Collision Theory Factors affecting rate : Energy of collisions Frequency of collisions

Temperature: 

Temperature Reaction : Marble chips with acid

Slide4: 

Normal High Temperature Lower Temperature

Slide5: 

Low Temperature Bang! Is it or is it not an effective collision? Maybe?

Slide6: 

Middle Temperature Bang! Is it or is it not an effective collision? Probably!

Slide7: 

High Temperature Bang! Is it or is it not an effective collision? Definitely !

Slide8: 

Normal High Temperature Lower Temperature

Effect of Temperature: 

Effect of Temperature Increase in Frequency of collisions AND Increase in energy of collisions

Surface Area: 

Surface Area Reaction : Marble chips with acid

Slide11: 

Marble Chips Marble Powder Large Marble Chunks

Slide12: 

Large Chunks Of Marble Bang! Is it or is it not an effective collision? Only on the outside

Slide13: 

Marble Chips Around the outside of each chip Bang! Is it or is it not an effective collision?

Slide14: 

Marble Powder Very fast with every tiny particle Bang! Is it or is it not an effective collision?

Slide15: 

Marble Chips Marble Powder Large Marble Chunks

Effect of Surface Area: 

Effect of Surface Area Increase in Frequency of collisions NO! Increase in energy of collisions

Concentration: 

Concentration Reaction : Marble chips with acid

Slide18: 

Bench Acid Strong Acid Dilute Acid

Slide19: 

Concentrated Acid Yes from all angles Bang! Is it or is it not an effective collision?

Slide20: 

Normal “bench” Acid Yes from most angles Bang! Is it or is it not an effective collision?

Slide21: 

Dilute Acid Only occasionally so very slow Bang! Is it or is it not an effective collision? HCl

Slide22: 

Bench Acid Strong Acid Dilute Acid

Effect of Concentration: 

Effect of Concentration Increase in Frequency of collisions NO! Increase in energy of collisions

Catalyst: 

Catalyst Reaction : Hydrogen Peroxide and Manganese IV oxide

Slide25: 

No Catalyst Catalyst

Effect of Catalyst: 

Effect of Catalyst

Effect of Catalyst: 

Effect of Catalyst Decrease in NO! Effect on frequency of collisions Activation Energy

Slide28:
