Equilibrium Flashcards
What is dynamic equilibrium?
When the rate of the forward reaction is the same as the backwards reaction. Concentration of reactions + products remain constant
What is the general equation for dynamic equilibrium?
A + B —> C + D
What is Le Chatelier’s Principle?
When a system in equilibrium is subjected to an external change the system readjusts itself to minimise the effect of that change
What would happen if you increased the concentration of reactants/products in equilibrium?
Equilibrium position would shift to the other side
What would happen if you decreased the concentration of reactants/products in equilibrium?
Equilibrium position would shift to the other side
What would happen if you increased the temperature of a reaction in equilibrium?
Equilibrium position would shift in the endothermic direction
What would happen if you decreased the temperature of a reaction in equilibrium?
Equilibrium position would shift in the exothermic direction
What would happen if you increased the pressure of a reaction in equilibrium?
Equilibrium position would shift in the side with the fewest moles of gas
What would happen if you decreased the pressure of a reaction in equilibrium?
Equilibrium position would shift in the side with the most moles of gas
What effect does catalysts have on the equilibrium position?
NONE
How do the rate of the forwards and reverse reaction increase?
By the same amount
What does enthaply change tell you in equilibrium reaction?
The reaction type of the forwards reaction
What happens when it shifts to the right?

What is the equation for the Haber process?
N2(g) + 3H2(g) —-> 2NH3(g)
What can Le Chatelier’s Principle be used to predict?
The best conditions needed to force the equilibrium to the right in order to produce the maximum yield
