Compressibility factor (i.e., the ratio of actual volume of gas to the volume predicted by ideal gas law) for all gases are

A Always greater than one
B Same at the same reduced temperature
C Same at the same reduced pressure
D Both B & C

Correct Answer: Both B & C

Since all the gases at same reduced pressure and temperature all the gases behaves similarly the compressibility factor will be same for all the gases.
