M5 - Topic 2: Factors that Affect Equilibrium

Question 1

What does le Chatelier’s principle state

Answer 1

A system in equilibrium that is distributed, will shift the position of equilibrium in the direction that counteracts the effect of disturbance

Question 2

what happens to equilibrium when there is an change in concentration (2)

Answer 2

favour side with less concentration

Question 3

what happens to equilibrium when the temperature of a chemical system change(2)

Answer 3

↑ temp = favour endothermic side

↓ temp = favour exothermic side

Question 4

what happens to equilibrium when pressure is changed within a system (2)

Answer 4

↑ pressure = favours side with less molecules

↓ pressure = favours side with more molecules

Question 5

what happens to equilibrium when a catalyst is added to the system (2)

Answer 5

increase the rate at which equilibrium is achieved

does not effect position of equilibrium
