C6: notes

• | rates of reactions

  reactions @ diff rates

  • the rate of reaction is how fast the REACTANTS are CHANGED into PRODUCTS
  • RATE OF REACTIONS: amt REACTANTS USED or PRODUCT FORMED ÷ time
• | rates of reactions

  understanding graphs

  • STEEPER line = FASTER rate of reaction_ becomes LESS STEEP
  • QUICKEST reactions r STEEPEST and become FLAT in the LEAST AMOUNT OF TIME

  
• | rates of reactions

  particles must COLLIDE w/ ENOUGH ENERGY in order to REACT

  • COLLISION THEORY: particles must collide w/ enough energy for a reaction to occur

  RATE of chemical reaction depends on:

  1. COLLISION of reacting particles_ MORE collisions = FASTER reaction
  2. energy TRANSFERRED during collision_ COLLISION THEORY

  • ACTIVATION ENERGY: MINIMUM amt particles need to react
  • particles need this energy to BREAK THE BONDS in the reactants & start reaction
