Question

At a constant temperature Ne, Ar and Xe deviate from ideal behavior according to equation  P = RT/V_m - b

Where b is vanderwaal's constant. The Z vs P graph would be steepest for which of the following

(1)   Ne

(2)  Ar

(3)  Kr

(4)  Xe

Answer 1

Correct option  (4)  Xe

Explanation:

At constant T, slop of Z vs P graph ∝ b

Xe has the maximum radii & hence maximum b & hence its graph will be steepest.
