Chemical Equilibrium

 $CO_2\ \left(g\right)\ +\ C\ \left(s\right)\ \leftrightarrow\ 2CO\ \left(g\right)$  

An increase in carbon dioxide shifts 

• Left (towards reactants)

• Right (towards products)

• Does not affect equilibrium

 $CO_2\ \left(g\right)\ +\ C\ \left(s\right)\ \leftrightarrow\ 2CO\ \left(g\right)$  

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

What symbol shows that a reaction is reversible?

• $\leftarrow$

• $\rightarrow$

• $\leftrightarrow$

• $=$

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
