Kinetics Review QUIZIZZ

A reaction is most likely to occur when reactant particles collide with

• proper energy, only

• proper orientation, only

• both proper energy and proper orientation

• neither proper energy and proper orientation

Increasing temperature of a reaction causes the rate of reaction to:

• increase due to more collisions between reactant molecules

• decrease due to more collisions between reactant molecules

• increase due to less collisions between reactant molecules

• decrease due to less collisions between reactant molecules
