Question:
Among the gases a, b, c, d, e, and f, the gases that show only positive deviation from ideal behavior at all pressures in the graph are:
Among the gases a, b, c, d, e, and f, the gases that show only positive deviation from ideal behavior at all pressures in the graph are:
Show Hint
If \( Z>1 \), the gas is less compressible and shows positive deviation from ideal behavior.

- b, c only
- b, c, a only
- d, e only
- d, e, f only
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Positive deviation from ideal behavior means compressibility factor \( Z>1 \) at all pressures. From the graph, curves for b and c lie completely above the line \( Z = 1 \), indicating that they show only positive deviation throughout.
