Unformatted text preview: Reaction Rates In a reaction reactants are converted into products The rate of the reaction can be defined as how quickly the concentration of product increases or how quickly the concentration of reactants decreases. Influences Concentration directly affects the reaction rate, higher concentrations make reactions run faster Temperature directly affects the reaction rate, increasing temperature makes the reaction run faster Catalysts a special chemical that enhances the speed of a reaction (faster) How do reactions work? The reactants must come into contact to react together. Both temperature and concentration will influence how many times a minute reactants collide with other reactants. Increasing a reaction rate Raise the temperature molecules move faster and collide more often Increase the concentration of reactants Do all collisions result in a reaction? NO!!!!!! Besides just colliding there are two very important factors to a successful reaction First is orientation: Second: Each atom must collide with enough kinetic energy to break its bonds In use:...
