Question 1

If a system at equilibrium is subjected to a change in conditions that disturb the equilibrium system, the system will proceed to a new equilibrium state in such a direction to partially offset the change in condition.

Answer 1

LE CHATELIER’S PRINCIPLE

Question 2

Le Chatelier’s Principle implies to

Answer 2

minimize the stress in response to the change in the system

Question 3

REMEMBER:

PV = nRT

where
n = number of moles
R = constant
T = temperature

Question 4

Relationship of Pressure to Volume

Answer 4

Inversely proportional

Question 5

IN A CLOSED CONDITION

Answer 5

THE MATTER CAN’T ESCAPE.
THE ENERGY CAN ESCAPE.

Question 6

no change in volume:
_________ effect in inert gas

Answer 6

NO EFFECT IN INERT GAS

Question 7

Change in volume: ______________ NUMBER OF PARTICLES

Answer 7

LOWER THE NUMBER OF PARTICLES

Question 8

EXOTHERMIC

Answer 8

release heat

Question 9

ENDOTHERMIC

Answer 9

absorb heat

Question 10

It speeds up the backward and forward reaction

Answer 10

CATALYST

Question 11

Equilibrium constant

Answer 11

Keq = [D]^d [C]^c
______________
[A]^a [B]^b

Question 12

Characteristics of K

Answer 12

1. REACTION SPECIFIC
2. CATALYST
3. FACTORS (concentration; pressure; inert gas; temperature; catalyst)
4. RELATED TO THE GIBBS FREE ENERGY
   ΔG = -RTlnKeq
5. Keq changes with Temperature
6. Krev= 1/ Keq
7. IF THE STOICH IS CHANGED, THE K CHANGES IN THE FF:
   A+B = C Keq
   3A + 3B = 3C 3 Keq
8. IF REACTION PROCEEDS IN A STEPWISE MANNER
9. SIMULATANEOUS REACTION
