Unit 8: Kinetics and Equilibrium Review

Front

What does the collision theory state?

Back

Atoms, ions, or molecules must collide in order to react.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

True or False: The higher the concentration of a solution, the less solutes it has in it.

Back

False.

Front

What can interval C in a potential energy diagram be changed by?

Back

Adding a catalyst.

Front

What activates the reaction of burning magnesium in a Bunsen burner flame?

Back

The reactants are activated by heat from the Bunsen burner flame.

Front

Define 'catalyst'.

Back

A substance that increases the rate of a chemical reaction without being consumed.

Front

What is the role of a catalyst in a chemical reaction?

Back

It lowers the activation energy required for the reaction.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb heat, while exothermic reactions release heat.

Front

What is a potential energy diagram?

Back

A graphical representation of the energy changes during a chemical reaction.

Front

What does the term 'rate law' refer to?

Back

An equation that relates the rate of a reaction to the concentration of its reactants.
