Explain the graph above to me. (Including het vocabulary terms catalyst, activation energy, exothermic/endothermic)

Read each question and choose the choice that best answers each question. 

Match the vocabulary terms to the correct definition.

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

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

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

Increasing concentration increases the rate of reaction

Increasing concentration makes the reaction go backwards

Increasing concentration decreases the rate of reaction

Increasing concentration does nothing

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

Which side of a chemical equation are the reactants?

What does activation energy refer to in a chemical reaction?

The heat produced by a chemical reaction.

The total energy after a reaction.

The minimum energy needed to start a reaction.

Energy from catalyst in a reaction.

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

By balancing the equations

By making the equation simple

By identifying the reactants

By identifying the products

What is this graph displaying?

Activation energy of an exothermic reaction

Activation energy of a combustion reaction

Activation energy of an endothermic reaction

Activation energy of a decomposition reaction

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

True

False

Are catalysts consumed in the chemical reactions they facilitate?

They transform into another substance

Only in some circumstances

Yes

No

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

True

False

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

It prevents the chemical reaction from occurring

It reduces the energy required to initiate the reaction

It increases the energy output of the reaction

It alters the chemical compounds participating in the reaction

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

Increased heat production in the reaction.

The reaction will not proceed.

The reaction will proceed faster.

It creates a new substance.

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

Lowers the activation energy required.

Increases the activation energy required

Provides additional activation energy.

Has no impact on activation energy.

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.

All reactions must have enough energy to start the reaction.

True

False

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

The reaction would change to a different one

The reaction would slow down

The reaction would speed up

The reaction would instantly stop

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

True

False

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

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.

True

False
