Chapter 7 - Kinetics and Equilibrium

Question 1

The change in concentration of a reactant or product with time.

Answer 1

Reaction rate

Question 2

Molecules need to collide in order for a reaction to take place.

Answer 2

Collision theory

Question 3

The energy that is needed to get reactants close enough together for a reaction to occur

Answer 3

Activation energy

Question 4

A substance that speeds up the rate of reaction by providing a lower energy pathway but does not undergo any change itself.

Answer 4

Catalyst

Question 5

A chemical reaction that can only be run in the forward direction; that is, the products do not react to form the reactants.

Answer 5

irreversible process

Question 6

The state in which the rate of the forward reaction is equal to the rate of the reverse reaction

Answer 6

chemical equilibrium

Question 7

States that when a chemical system is at equilibrium and is disturbed by a stress, the system will respond by attempting to counteract that stress until a new equilibrium is established.

Answer 7

Le Châtelier’s Principle
