Collision Theory states three conditions that must be met for a reaction to occur.

Below are two of the three conditions, check them.

• particles must be in gaseous state

• particles must collide

• particles must be at standard conditions

• Activation Energy must be greater than the Kinetic Energy

• particle Kinetic Energy must be larger than Activation Energy

The third condition of Collision Theory states that particles must collide with the correct ______________________

Check all the factors that affect the rate of reaction

• temperature

• catalyst

• volume of solution

• surface area / particle size

• concentration

The image shows a Maxwell-Boltzmann distribution for a reactant at Situation A. What change could have caused Situation B and produced a faster rate.

• increase in temperature

• addition of a catalyst

• smaller particle size(more surface area)

• lower pressure

A reaction is run under conditions A.

What change could produce Graph B.

Select all the answers that apply.

• add a catalyst

• increase the temperature

• increase the pressure

• smaller particle size(increase surface area)

• increase the concentration

What possible change(s) could produce graph B from graph A

• remove catalyst

• use a lower concentration solution

• decrease the pressure

• decrease the temperature

Which of the following changes would produce the same amount of product, but faster

• change the temperature

• add a catalyst

• increase the pressure

• higher concentration of solution

• increase the temperature

Taking a solid reactant and crushing it into tiny pieces does which of the following:

• decrease the initial rate

• smaller particles have more surface area

• lowers the activation energy

• increases the initial slope of the graph

The ONLY factor that affects the Activation Energy is

• temperature

• surface area

• catalyst

• pressure

• concentration

What is an appropriate label for the dark blue area indicated by A

• particles that can react at the lower temperature

• particles that can react at the higher temperature

• particles that cannot react at the lower temperature

• particles that cannot react at the higher temperature
