# Density and Allotropes

APCHEM-KXU48K

Researchers are attempting to modify buckyballs to fit the section of the HIV molecule that binds to proteins, possibly inhibiting the spread of the virus.

Buckyballs and graphite are both allotropes of carbon:

$$C_{\text{(graphite)}}⇄ C_{\text{(buckyball)}}$$

The density of graphite is about 2 g/ml, and the density of a buckyball is about 1.5 g/ml.

A scientist would like to maximize the amount of buckyballs produced at very high temperatures to help her HIV research.

Which of the following should this scientist do to maintain the desired state of matter?

A

Maintain extremely low pressure.

B

Apply extremely high pressure.

C

Remove molecules of graphite.

D

The equilibrium will remain unchanged by changes to the system.
