Question

Chemically unreactive three different gases $A, B$ and $C$ of molecular masses $16, 32$ and $64$ are enclosed in a vessel at constant temperature till equilibrium is reached. Which of the following statements is true?

• A. Gas $A$ will be at the top of the vessel
• B. Gas $C$ will be at the top of the vessel
• C. Gas $C$ will be at the bottom of the vessel
• D. Gases will form homogeneous mixture

Answer 1

Answer: (D)

Gases will form homogeneous mixture

Answer 2

The gases $A, B$ and $C$ are chemically unreactive hence they will form a homogeneous mixture.
