The Maxwell Boltzmann Distribution

Cards (7)

  • Label the Maxwell Boltzmann distribution curve.
    Label the missing gaps with the correct annotations:
    A) Most probable energy
    B) Average energy
    C) Activation energy
    D) Number of molecules
    E) Energy
  • State and explain the key features of the Maxwell Boltzmann distribution curve.
    • Curve originates at the origin -> indicates that no molecules have zero kinetic energy
    • Rises sharply to a peak -> represents the most common kinetic energy level among the molecules
    • The total area under the curve is equivalent to the total number of molecules
    • The peak of the curve shows the most probable kinetic energy a molecule can have
  • Explain how increasing temperature increases the rate of a reaction.
    • As temperature increases, particles have more kinetic energy
    • Particles also more likely to have the activation energy
    • Leads to higher frequency of successful collisions
  • What is the Maxwell Boltzmann distribution?
    The distribution of molecular energies in gases
  • Describe the effect of increasing temperature on the Maxwell Boltzmann distribution curve.
    • When temp is increased, the peak of the distribution curve is lower and shifted to the right
    • the total area under the curve remains the same
    A) Higher temp
    B) Lower temp
  • Which part of the curve is equal to the total number of gas molecules?
    The area under the curve
  • Explain why a small increase in temp results in a large increase in the rate of reaction.
    • small increase in temp shifts distribution curve to the right
    • This indicates that both the rate of collisions and the proportion of collisions that lead to successful reactions increase with temp
