Unit 8 Classwork

Which factors increase the rate of a reaction?

• increasing temperature

• increasing concentration

• increasing surface area

• all of these

How can you increase the rate of a reaction?

• Decrease the pressure

• Decrease the concentration

• Increase the concentration

The word for a substance created in a chemical reaction...

• Reaction

• Reactant

• Product

• Mass

The speed at which a chemical reaction occurs

• Fast

• Slow

• Rate

• Ratio

The amount of something; how many particles in a volume of a mixture

• Rate

• Collision

• Catalyst

• Concentration

How is this equipment being used to measure the rate of reaction?

• The gas syringe measures how much gas is produced in a certain time

• The reaction mixture will increase in volume in a certain time

What is the activation energy?

• The energy of the products
• The energy of the reactants
• The minimum energy needed by the reactants to form the products.
• The energy lost in the reaction

According to collision theory, what must the reactants have in order to form products?

• The right size
• The right shape
• Enough energy
• Nothing

What kind of reaction is this?

• Endothermic
• Exothermic
• Cannot be determined

What letter represents the energy of the products?

• A
• B
• C
• D
