Chapter 12.2 - Factors Affecting Reaction Rates

What 6 main factors affect reaction rates?

Reactant’s chemical nature, amount of surface area, temperature, concentration, catalysis, collision theory

As you move down a group, the alkali metals react at a ______ rate with water

faster

The rate of most reactions increase with ________ _______ _________ between reactants

increasing surface area

Reaction rates normally _______ with temperature and concentration

increase

Chemical reactions occur as the results of ________ between reactant molecules

collisions

A higher ________ of reactant molecules makes molecules more likely to collide and react

concentration

When reactants are _______, collisions occur less frequently, causing the reaction rate to _______

consumed, decrease
