Chp 8 Rates of reaction

List three collision theory

(a)  

Collision that produces a reaction is called

(a)  

* same mass of solid

Choose the correct statement

• larger pieces of solids have a larger surface, more atoms are available to react. Meanwhile, the rate of reaction increases.

• smaller pieces of solids have a larger surface, More atoms are available to react. Meanwhile,

  the rate of reaction increases.

Activation energy is the minimum amount of energy needed for a collision to occur 

• True

• False

Describe the effect of temperature of the picture, choose the correct words below:

Temperature of the reaction increased/decreased, the particles move slower/ faster. They collide more often/ lesser, and with more / lesser energy.

• decreased, slower, lesser, lesser

• increased, slower, lesser, more

• increased, faster, more often, lesser

• increased, faster, more often, more

Diagram A and diagram B
which diagram have the higher temperature?

• Diagram A

• Diagram B

• two factors which can be investigated using the disappearing cross reaction:

• Changing the temperature

• Changing the volume of solution

• Changing the concentration of the HCl

How the rate of reaction can be measured?

• by measuring how much of the product has been made in a given time

• by measuring the temperature change of the reaction mixture in a given time.

• • by measuring how much of the reaction mixture has changed color over time.

• 1. by measuring the temperature change of the reaction mixture in a given time.

What does the graph tell you, when the slopes are steeper?
