Equilibrium

What symbol shows that a reaction is reversible?

Shift right means (reactant + reagent -> products)

• Towards products

• Want to make more reactants

• Toward reactants

Removing a reactant causes the reaction to shift in which direction (reactants + reagents -> products)

• Left

• Right

• It doesnt

Decreasing the volume

• Shift towards the side with LESS moles

• Shift towards the side with MORE moles

• Speed up the reaction and shift the equilibrium

• Speed up the reaction and NOT affect equilibrium

Write the equation for the equilibrium constant:

Le Chatelier's Principle states that if a chemical system at equilibrium is stressed,

• the system will adjust to increase the stress

• the system will adjust to reduce the stress

• the system will not adjust

For the reaction... SO₂ + O₂ <−> SO₃ If the concentration of SO₂ is increased, the system will shift ___________.

• left

• right

• left and right

• neither left nor right

For the reaction... heat + N₂ + O₂ ↔ 2NO If heat is added to the chemical system, the system will shift _______.

• left

• right

• left and right

• neither left nor right

2SO₂ (g) + O₂ (g) ⇌ 2SO₃ (g)

Decreasing the volume of container will

• shift the system right

• shift the system left

• change K

• have no effect
