QNEET-2019-Ch-746: NEET 2019 Chemistry - Class 11 NEET-2019-Ch-746 Solution: A gas at 350 K and 15 bar has molar volume 20 percent smaller…
A gas at 350 K and 15 bar has molar volume 20 percent smaller than that for an ideal gas under the same conditions. The correct option about the gas and its compressibility factor (Z) is - Z < 1 and attractive forces are dominant Z < 1 and repulsive forces are dominant Z > 1 and attractive forces are dominant Z > 1 and repulsive forces are dominant
Multiple Choice Options
- A Z < 1 and attractive forces are dominant
- B Z < 1 and repulsive forces are dominant
- C Z > 1 and attractive forces are dominant
- D Z > 1 and repulsive forces are dominant
Step-by-Step Verified Solution
Compressibility factor (Z ) = V r e a l V i d e a l
Here, V real < V ideal . Therefore, Z < 1.
In gaseous molecules attractive forces are dominant.
