• temperature

• concentration

• surface area

• volume

• catalysts

A temperature increase causes the particles ......

• to slow down

• move faster

• collide higher

• in the right order

Why does a higher concentration increase the rate of reaction?

• it increases the amount of reactants

• it lowers the activation energy

• it increases the energy of particle collisions

• it increases the frequency of particle collisions

What is the rate of reaction?

• How fast a reaction is 
• How big a reaction is
• How loud a reaction is
• How much gas a reaction produces

• concentration
• surface area
• temperature
• reactants

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

An increase in carbon dioxide shifts 

• Left (towards reactants)

• Right (towards products)

• Does not affect equilibrium

Increasing temperature favors

• Gases

• Liquids

• Endothermic reactions

• Exothermic reactions

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
