Imagine that you fill a shallow tray with water and place a drop of red ink in one end of the tray and a drop of green ink in the other end. Which of the following is TRUE at equilibrium?
A) The red and green ink do not mix at all.
B) The concentration of each ink is higher at one end of the tray than at the other end.
C) The red ink is uniformly distributed in one half of the tray, and the green ink is uniformly distributed in the other half of the tray.
D) No predictions can be made without knowing the size of the ink molecules.
E) The red and green inks are both uniformly distributed throughout the tray.

At equilibrium, due to the process of diffusion, both the red and green inks will be uniformly distributed throughout the tray, resulting in a uniform mixture of colors across the entire tray. Diffusion allows particles to move from areas of higher concentration to areas of lower concentration until a uniform distribution is achieved.
