Test Description: Thermochemistry and equilibrium activity
Instructions: Answer all questions to get your test result.
1) What is heat?
A
a measure of the amount of heat an object has
B
Energy that is transferred between objects, represented by the letter q
C
fuel from an engine
D
a change in temperature
2) What is temperature?
A
Energy that is transferred between objects, represented by the letter q
B
A measure of the amount of heat an object has
C
Heat always travels from the warmer object to the cooler object
D
A reaction where energy is absorbed from the surroundings
3) What is the Law of conservation of energy?
A
Since it absorbs heat, it would feel cold
B
A reaction where energy is absorbed from the surroundings
C
In any chemical or physical process energy is neither created nor destroyed.
D
Energy that is transferred between objects, represented by the letter q
4) What is an endothermic reaction?
A
A measure of the amount of heat an object has
B
A reaction where energy is released from the system
C
A reaction where energy is absorbed from the surroundings
D
A reaction in which energy is released to the surroundings
5) What would an exothermic reaction feel like?
A
Since it is releasing heat, it feels HOT
B
A measure of the amount of heat an object has
C
Since it is releasing heat, it feels COLD
D
Since it absorbs heat, it would feel cold
6) What is heat capacity?
A
It is the amount of heat needed to increase the temperature of an object exactly 10C. Heat capacity depends on both mass and
B
A reaction where energy is absorbed from the surroundings
C
heat required for a reaction for a chemical reaction
D
In any chemical or physical process energy is neither created nor destroyed.
7) What happens to temperature during a change of state?
A
While the substance is changing the temperature decreases
B
While the substance is changing the temperature increases and decreases
C
While the substance is changing the temperature remains constant
D
While the substance is changing the temperature increases
8) What is the activated complex?
A
energy changes in a reaction
B
reactants
C
products
D
Transition state (It is when the atoms have reached the highest energy. It only lasts a very short time. )
9) How does a catalyst affect the rate of reaction?
A
Catalysts has no affect on the rate of reaction
B
Catalysts lower the activation barrier making it harder for the atoms to reach the activation point.
C
Catalysts lower the activation barrier making it easier for the atoms to reach the activation point.
D
Catalysts increases the activation barrier making it easier for the atoms to reach the activation point.
10) When a reaction is at equilibrium what happens when more reactant is added?
A
There will be more product than reactant
B
More reactant will cause the equilibrium to shift toward the product
C
There will be some reactant and some product
D
It will not affect the reaction
