Maxwell-Boltzmann Graph

APCHEM-OL8I1M

Based on the Maxwell-Boltzmann graph showing the number of molecules for a gas versus the speed of the molecules, which of the following indicates that a unimolecular reaction will occur with a faster rate?

A

Dealing with a gas indicates that the molecules will only react when the molecules collide with the container due to the wide distribution of the particles.

B

Increasing the pressure of the system will force the molecules closer together, increasing the number of collisions resulting in a faster reaction.

C

A homogeneous catalyst must be used to start any unimolecular reaction involving gases.

D

Decreasing the temperature of the system will increase the average kinetic energy of the molecules, resulting in a greater number of collisions needed to start the reaction.
