Fugacity is a measure of the____________________?
Correct answer: B. Escaping tendencies of the same substance in different phases of a system
- A. Relative volatility of a mixture of two miscible liquids
- B. Escaping tendencies of the same substance in different phases of a system
- C. Behaviour of ideal gases
- D. None of these
Explanation
Fugacity represents a component's effective escaping tendency from a phase, allowing phase equilibrium to be expressed by equal fugacities. It is not a measure of relative volatility or restricted to ideal gases.
