The Z vs P graph of four gases at the same temperature is given below. Which gas has the lowest critical temperature?

Z vs P graph

Answer:

Solution:

A deeper dip of Z below 1 means a larger $a / b$ , and $T_{c} = 8 a / (27 R b)$ is larger when $a / b$ is larger.

G has the shallowest dip (nearest to ideal), so it has the lowest critical temperature.

Answer: (C).
