Equilibrium 1 3.2.3

Question 1

Define Dynamic Equilibrium?

Answer 1

When the forwards and reverse reaction occur at the same rate in a closed system

Question 2

What are characteristics of Dynamic Equilibrium?

Answer 2

Rates of forwards and reverse reactions are equal.
It is in a closed system (nothing is added, nothing is removed).
Concentrations remain constant

Question 3

What is the Le Chatelier Principle?

Answer 3

When a system in dynamic equilibrium is subject to change the system will adjust to minimise change

Question 4

What is the Haber Process?

Answer 4

The process used in the production of Ammonia

Question 5

What is the equation of the Haber Process?

Answer 5

N2 + 3H2 →2NH3

Question 6

What conditions maximise the Haber Process and why?

Answer 6

High Pressure:
Fewer moles of gas on the RHS
Low Temperature:
Forwards reacton is Exothermic

Question 7

What conditions does industry use for the Haber Process and why?

Answer 7

High Pressure: 200000kPa (200atm)
As fewer moles of gas on the RHS
Medium Temperature: 400-450 Celcius
As reaction is faster to maximise production
Iron Catalyst:
Offers alternative reaction path
