The major theory of reaction rate is called

• Thermodynamics

• Collision Theory

• Newton's Law

• Crash Thoery

An increase of temperature would:

• Slow reaction rate

• Speed up reaction rate

• Wouldn't change the reaction rate

• Would Stop the Reaction from occuring

Order them from smallest to largest amount of surface area.​

• A Rock

• Rock Broken into 5 Peices

• Rock Cuched to Dust

What could be a reason that the reaction rate has been increased

• An increase in Water added to solution

• There are more Bubbles

• The Chalk is a different colour

• The Concentrate of the Acid has been increased

Increasing Pressure causes the reacting particles

• to bond together

• gain more kinetic energy

• to move closer together

• to repel from each other

Which of the following is NOT a key concpet of collision theory

• Particles must ollide in order to react

• Particles must move slowly when they collide, otherwise they smply "bouce off" one another

• Particles must collide with the proper orientation

• Particles must collide with sufficient energy to reach the activated complex in order to react

• Particles that collide will always end up succecfully joining

What is Activation Energy

• The speed at which a molecule or atom vibrates per second

• The maximum amount of energy that is required to activate molecules to undergo chemical thransformation or physical transport

• The minimum amount of energy that is required to activate moliclues to undergo chemical transformation or physical transport

• The energy that makes the Atom
