APCHEM-NU8J5G

In the following graphic, the substance is contained in a sealed box. The substance on the left is at a lower temperature than the substance on the right. The same molecular composition is present in each box.

Which of the following explains why molecules become more dispersed, as shown, when the temperature of the system is increased?

A

The particles gain enough energy to overcome the activation energy needed to react forming gas particles.

B

The particles show an increase in vibrational energy, which allows for intramolecular bonds to be broken.

C

The particles gain enough energy to overcome the intermolecular forces, allowing a change in state for the substance.

D

The particles show an increase in rotational energy, which diminishes adherence to the container, allowing for dispersion throughout the container.
