Reaction Rates

List four factors that affects the rate of a reaction

• temperature

• concentration

• surface area

• volume

• catalysts

A temperature increase causes the particles ......

• to slow down

• move faster

• collide higher

• in the right order

What does NOT happen when the temperature is increased?

• Particles collide more often
• Particles collide with more energy
• Particles move faster
• More particles collide in the correct orientation

What makes an effective collision?

• When molecules collide.
• When molecules collide with the proper orientation.
• When molecules collide with proper orientation and enough kinetic energy.
• High Temperature.

What is the rate of reaction?

• How fast a reaction is 
• How big a reaction is
• How loud a reaction is
• How much gas a reaction produces

Located on the left side of the reaction

• reactants
• products

The minimum amount of energy needed for colliding particles to react is called

• Chemical Energy

• Kinetic Energy

• Activation Energy

• Potential Energy

Grinding a seltzer tablet into powder increases the rate of reaction due to increased

• concentration
• surface area
• temperature
• reactants

Which factors increase the rate of a reaction.

• increasing temperature
• increasing concentration
• increasing surface area
• all of these

You add more bodies into a "mosh pit" to hope for more collisions.  You have increased-

• temperature
• concentration
• pressure
• catalyst
