When argon is placed in a container of neon,the argon spontaneously disperses throughout the neon because ________.
A)of the large attractive forces between argon and neon atoms
B)of hydrogen bonding
C)a decrease in energy occurs when the two mix
D)the dispersion of argon atoms produces an increase in disorder
E)of solvent-solute interactions

Question

Quizplus · Accepted Answer

The dispersal of the argon atoms in the neon gas results in an increase in disorder or entropy. This is due to the random movement of the individual atoms and the lack of organization in the mixture. The other options, such as hydrogen bonding, solvent-solute interactions, and attractive forces between the atoms, are not relevant or significant enough to explain the spontaneous dispersal of the argon in the neon. While a decrease in energy may occur, it is not the primary reason for the dispersal.
