Module 5 - Section 1 [Static and Dynamic Equilibrium]

Question 1

Recall the types of equilibrium

Answer 1

Types of equilibrium:
- Dynamic equilibrium
- Static equilibrium

Question 2

Recall features of static equilibrium

Answer 2

Features of Static Equilibrium:
- Reaction only occurs in one direction → irreversible
- The forward and reverse reaction rate = 0
- Macroscopic and microscopic properties are unchanged
- Includes limiting reagents

Question 3

Recall features of dynamic equilibrium

Answer 3

Features of Dynamic Equilibrium:
- Reversible reaction
- Closed system
- The forward is equal to the reverse reaction rate
- Macroscopic properties are constant
- Microscopic properties are changing

Question 4

Recall macroscopic properties

Answer 4

Macroscopic Properties can be observed by the naked eye:
- Pressure
- Concentration
- Colour

Question 5

Define steady state system

Answer 5

Steady State System is a system where reactants are being added and products are being removed and to an outside observer, would be at equilibrium

Question 6

Define homogenous equilibrium

Answer 6

Homogeneous Equilibrium is an equilibrium that has only a singular state of matter

Question 7

Define heterogenous equilibrium

Answer 7

Heterogeneous Equilibrium is an equilibrium that has more than one state of matter

Question 8

Define closed system

Answer 8

Closed System involves the transfer of energy but not matter between the system and the surroundings

Question 9

Define open system

Answer 9

Open System involves the transfer of energy and matter between the system and the surroundings

Question 10

Relate reversibility to Gibbs free energy

Answer 10

ΔG < 0, the reaction is not reversible as the reverse reaction has ΔG > 0
