REACTION RATES: KINETICS

REACTION RATES KINETICS

• Rate that reactants turn into products
• 5 FACTORS AFFECTING REACTION RATES
• 1. temperature incr. temp INCREASES
• rxn rates
• Why? particles move faster and collide
  with greater intensity

2

• 2. surface area increasing will cause reaction
  rate to increase
• Why? greater exposure of reacting
  particles to each other
• examples pulverizing, crushing, chopping
  up, etc.
• 3. agitation increases reaction rate
• Why? increases likelihood ofparticles being
  exposed to one another increase in collisions
• examples shaking, stirring

3

• 4. concentration increasing concentration of
  reactants increases rate
• Why? increasing particles increases
  chance of collision resulting in a reaction
• 5. catalysts substance that increases the
  reaction rate without being used up in the
  reaction.
• Why? lowers the ACTIVATION energy
• sort of invites reacting particles together
  so they will react
