Chemical Equilibrium

Adding a catalyst will

• Shift Left (towards reactants)

• Shift Right (towards products)

• Speed up the reaction and shift the equilibrium

• Speed up the reaction and NOT affect equilibrium

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

An increase in carbon monoxide shifts 

• Left (towards reactants)

• Right (towards products)

• Does not affect equilibrium

What symbol shows that a reaction is reversible?

Forward reaction is

• Reactants to products (left to right)

• Products to reactants (right to left)

• Always reversible

• Always endothermic

Shift right means (reactant + reagent -> products)

• Towards products

• Want to make more reactants

• Toward reactants

• Left

• Right

• It doesnt

In the equilibrium expression, K represents

• the reactants' concentration

• the products' concentration

• the rate constant

• the equilibrium constant
