3.1.5 Kinetics

Cards (5)

  • Rate of reaction
    (Change in concentration of a substance/ time)= rate of reaction
  • Activation energy is the minimum energy required with which particles must collide in order for a reaction to occur
  • Maxwell-Boltzman Curve shows how energies of molecules in a gas is distributed.
    The area under the curve represents the amount of molecules
    A) Number of molecules
    B) Energy
    C) Most probable energy
    D) Average energy
    E) Molecules with sufficient activation energy
    F) Activation energy
  • An increase in temperature increase the rate of reaction
    As more molecules have an energy greater or equal to the activation energy
    Therefore meaning more successful collisions occur per unit of time leading to a faster reaction
  • A catalyst is a substance that speeds up a chemical reaction by providing an alternative route with a lower Ea without being used up. Increasing the rate of the forward and backwards reaction at the same time
