TERM 1
What is kinetics?
DEFINITION 1
The rate and mechanism of a reaction
TERM 2
What happens to a reaction if the
concentration of the reactants is decreased?
DEFINITION 2
The rate of the reactions decrease
TERM 3
How does an increase in temperature affect
rate of reaction?
DEFINITION 3
The rate of all reactions increases
TERM 4
How does surface area affect the rate of
reaction?
DEFINITION 4
Increasing the surface area of the reactants will increases the
rate of reaction
TERM 5
What is a catalyst?
DEFINITION 5
A substance that decreases the activation energy and speeds
up the reaction . It does not change the overall process. It
does not get involved in the chemical reaction as a product
or reactant.

rate of reaction

TERM 5

What is a catalyst?

DEFINITION 5

A substance that decreases the activation energy and speeds

up the reaction. It does not change the overall process. It

does not get involved in the chemical reaction as a product

or reactant.

What is activation energy?

The minimum amount of energy needed to start the reaction

TERM 20

What are the types of equilibrium?

DEFINITION 20

1) Phashe Equilibrium2) Chemical Equilibrium

What is a dynamic equilibrium?

A reaction in which both forward and backward reactions are

constantly occurring.

TERM 22

Phase Equilibrium

DEFINITION 22

equilibrium occurring between phases. Can only happen from

S-L, L-S, G-L, L-G. No skipping of phases

TERM 23

Chemical Equilibrium

DEFINITION 23

when the concentration of the reactants and the products

remain constant while the reaction continues to occur

(dynamic equilibrium)
