Chemical Equilibrium Flashcards
1
Q
What is meant by chemical equilibrium?
A
It is the state in which the rate of the forward reaction is equal to the rate of the reverse reaction
2
Q
State Le Châtelier’s Principle
A
When a system at equilibrium is subject to stress, the position of the equilibrium will change to minimise the effect of the stress
3
Q
What happens when you increase the pressure?
A
Goes to the side with a lower number of molecules
4
Q
What happens when you decrease the pressure?
A
Goes to the side with a higher number of molecules
5

A
Goes in the endothermic direction
6
Q
What happens when you decrease the temperature?
