Factors Affecting Reactions
True/False
100


What is Collision Theory?

Particles that collide to cause a reaction to take place.

100

Factor that increases the rate of collisions due to increased average kinetic energy

What is temperature?

100

Chemical reactions tend to slow down when the temperature rises.

False


200

Something that can lower activation energy, or speed up a reaction.

What is a catalyst?

200

Factor that results in more collisions due to the presence of more particles in a certain space

What is concentration?

200

Increasing the total surface area of solid or liquid reactants increases the rate of the reaction

True

300

Minimum energy required for a reaction to take place.

What is activation energy?

300


What is the reaction rate equation?

R= -change [A]/change t

300

Once a chemical reaction starts, the reacting particles no longer have to collide for products to form.

False

400

The conversion of reactants to products, and products to reactants occur simultaneously. 


These reactions never go to completion.

What is a reversible reaction?

400


Name four factors affecting reactions.

Temperature, particle size, concentration, and catalysts

400

The reaction rate is usually expressed as the amount of time per change in amount of reactant or product

False

500

If stress is applied to a system in chemical equilibrium, the system changes in a way that releases stress. 

Le Chatelier's Principle states what?

500


What is they take part in the reaction and help to speed it up without being consumed in the process?

Explanation of why catalysts are not considered a reactant

500

A type of stress is considered change in temp, pressure, and concentration.

True
