What two factors govern whether a collision between reacting particles will be effective?

• orientation and potential energy 
• kinetic energy and temperature 
• kinetic energy and orientation 
• potential energy and kinetic energy 

Why does a higher temperature increase the rate of a reaction?

• it increases both the frequency and energy of particle collisions
• it only increases the frequency of particle collisions
• it only increases the energy of particle collisions
• it reduces the activation energy of the reaction
