Question 1

What is Le Chateliers principle?

Answer 1

When a reaction is in equilibrium, if there is a change to the conditions, the system will respond to counteract the change and restore the conditions

Question 2

If the concentrations of the reactants increase what will happen to a reaction in equilibrium?

Answer 2

The equilibrium will shift right to produce more of the products

Question 3

If the concentration of the products decreases what will happen to the equilibrium?

Answer 3

The equilibrium will, shift left to produce more of the reactants

Question 4

What will happen to an equilibrium if the temperature increases.

Answer 4

The equilibrium will shift so the endothermic reaction will be favoured in order to decrease the temperature

Question 5

What will happen to the equilibrium if the temperature decreases?

Answer 5

The equilibrium will shift to favor the exothermic reaction in order to increase the temperature

Question 6

What is the effect if increasing the pressure on a reaction in equilibrium

Answer 6

The equilibrium will shift to favor the side that has fewer moles of gas in order to decrease the pressure
