Factors affecting chemical equilibrium

Question 1

Le Châtelier’s principle

Answer 1

States that if a stress is applied to the system at equilibrium the system shifts in the direction that relieves the stress. 

Question 2

What’s a stress

Answer 2

A stress is any kind of change in a system at equilibrium that upsets the equilibrium

Question 3

Any increase in the concentration of a reactant results in

Answer 3

a shift to the right and additional products

Question 4

Desiccant

Answer 4

A substance that absorbs water

Question 5

How would the equilibrium system react if a chemist removed a product ( H2O) 

Answer 5

The equilibrium shifts in the direction that will bring the concentration of water back up

It will shift to the right which will result in additional product

Question 6

True or false:
In any equilibrium the removal of a product result in a shift to the right in the production of more product

Answer 6

True

Question 7

How to make an equilibrium shift to the left

Answer 7

If additional product is added to a reaction at equilibrium the reactants shift to the left. The stress is relieved by converting products to reactants

Question 8

How does volume affect equilibrium

Answer 8

Decreasing the volume increases pressure which adds stress to the equilibrium.

Question 9

True or false

Answer 9

If the number of moles of gas is the same on both sides of the equation changes in volume and pressure have no effect on the equilibrium

Question 10

How does increasing the temperature affect equilibrium

Answer 10

If heat is added to an equilibrium system the equilibrium shifts in the direction in which the heat is used up that is it will shift to the left.

Lowering the temperature shift the equilibrium to the right because the forward reaction liberates heat and relieves the stress
