At a given temperature T, gases Ne, Ar, Xe and Kr are found to...
At a given temperature gases and are found to deviate from ideal gas behaviour. Their equation of state is given as at Here, is the van der Waals constant. Which gas will exhibit steepest increase in the plot of (compression factor) vs 
Options
- A
- B
- C
- D
Correct answer
D.
Step-by-step solution
As the increases the slope increases. We know that represents the effective size of the molecules. Since, Xe has the biggest size among given noble gases because on moving down the group size increases due to increase in shell, hence Xe will have the highest slope.
