1

Match the vocabulary terms to the correct definition.

Draggable item		Corresponding Item
Inhibitor		An increase in this will typically increase the rate of reaction. It is measured by hot hot or cold a substance is.
Exothermic		A material is used to decrease the speed of a chemical reaction.
Surface Area		The amount of substance in a given volume.
Catalyst		Lowers activation energy for the reaction to begin
Endothermic		The minimum amount of energy needed for a reaction to take place.
Concentration		This reaction will release heat into the surrounding area.
Temperture		This reaction will absorb heat from the surrounding area.
Activation Energy		The area of the chemical substances used in a chemical reaction.

This image above best represents what type of chemical reaction? Explain your answer.

Required

1

When we increase the amount of concentration of a substance, how are we affecting the rate of reaction?

Required

1

Draggable item		Corresponding Item
PBSO4 --> PBSO3 + O2		Combustion
MG + FE2O3 --> FE + MGO		Double Displacement
C2H4 + O2 --> CO2 + H20		Decomposition
NABR + HPO4 --> NA3PO4 + HBR		Single Replacement

Required

1

Which side of a chemical equation are the reactants?

Required

1

What does activation energy refer to in a chemical reaction?

Required

1

How do we comply with the law of conservation of matter with chemical equations?

1

What is this graph displaying?

1

In an endothermic reaction, the products have less energy than the reactants because energy is released.

Required

1

Are catalysts consumed in the chemical reactions they facilitate?

1

Increasing the surface area of the reactants will decrease the rate of the reaction.

Required

1

Which accurately describes the function of a catalyst in a chemical reaction?

Required

1

What happens if the activation energy in a chemical reaction is not reached?

Required

1

How does a catalyst affect the activation energy of a reaction?

Required

1

The human body has chemical reactions happening all the time. If we increase this in your saliva the food in your mouth will break down faster.

1

All reactions must have enough energy to start the reaction.

Required

1

What would likely happen if you remove a catalyst from a chemical reaction?

1

Heat gives the reactant particles more energy. You can increase the surface area and concentration or also use a catalyst it speed up the reaction

Required

1

What type of reaction is shown below?
CA(OH)2 + AL2(SO4)3 --> CASO4 + AL(OH)3

1

If you change the concentration of a substance, that means you are adding more of that substance to the same given volume. This will make the reaction slow down.
