3.5 Kinetic Molecular Theory

Multiple Choice

In examining the Maxwell-Boltzmann distribution curves at different temperatures on the graph below, which variable in the graph remains the same?

• the area under each curve

• the average kinetic energy of the particles 

• the temperature in ^oC

• the height of each peak 

Multiple Choice

Why does a higher temperature increase the rate of a reaction?

• it increases both the frequency and energy of particle collisions
• it only increases the frequency of particle collisions
• it only increases the energy of particle collisions
• it reduces the activation energy of the reaction

Multiple Choice

This question is about the Maxwell–Boltzmann distribution of molecular energies in a sample of a gas shown in the figure below.

What does the area under the curve represent?

• The total energy of the particles.

• The total number of particles.

• The number of particles that can react with each other.

• The total number of particles that have activation energy.

Multiple Choice

Which of the following pairs of Maxwell–Boltzmann distribution curves best represents the distribution of kinetic energy for particles at two different temperatures?

Note: dashed line = higher temperature, solid line = lower temperature.
