- 4. Multiple Choice
Which group of particles shows that increasing surface area increases collisions among particles?
Left side
Right side
Cannot be determined by either picture
- 5. Multiple ChoiceDecreasing the particle size increases the reaction rate becauseIt makes particles move fasterIt increases the likelihood of collisions with the correct geometryIt decreases the surface area available to reactIt increases the number of collisions
- 6. Multiple ChoiceProducts will form faster if____________the particle size of the reactants are larger.temperature is decreased.concentration of the reactants are increased.the reaction is not stirred.
- 7. Multiple ChoiceWhy does a higher temperature increase the rate of a reaction?it increases both the frequency and energy of particle collisionsit only increases the frequency of particle collisionsit only increases the energy of particle collisionsit reduces the activation energy of the reaction
- 8. Multiple Choice
Decreasing the particle size increases the reaction rate because
It makes particles move faster
It increases the likelihood of collisions with the correct geometry
It decreases the surface area available to react
It increases the surface area of the reactants thus more particles collides with each other therefore increase the frequency of effective collisions
- 9. Multiple ChoiceAdding a catalyst to a chemical reaction changes the rate of reaction by causinga decrease in the activation energyan increase in the activation energya decrease in the heat of reactionan increase in the heat of reaction
- 10. Multiple ChoiceWhich interval represents the activation energy of the forward reaction?ABCE
- 11. Multiple ChoiceWhich numbered interval on the diagram would change when a catalyst is added?B & CC & DE & CA & D
- 12. Multiple Choice

R
W
X
There is no catalyst.
- 13. Multiple Choicestep 1: O3 → O2 + O
step 2: O3 + O → 2 O2
