Round 3 — Rates of Reaction

Increasing temperature will:

• Slow reactions

• Decrease collisions

• Stop reactions

• Increase collisions between particles

Grinding a tablet increases reaction rate because of increased:

• Concentration

• Surface area

• Temperature

• Volume

A substance that speeds up a reaction without being used up is called:

• Catalyst

• Product

• Reactant

• Solute

Products will form faster if:

• Surface area is smaller

• Temperature is decreased

• Concentration is increased

• Reaction is not stirred

More collisions result in:

• Slower reaction

• Faster reaction

What is the rate of reaction?

• How fast a reaction occurs

• How big a reaction is

• How loud it is

• How much gas forms
