Identify the speed distribution functions of $\mathrm{Ne}, \mathrm{Ar}$ and Kr with the curves in the figure above:

(a)Ne-A, Ar-B, Kr-C

(b)Ne-B, Ar-C, Kr-A

(c)Ne-C, Ar-B, Kr-A

(d)Ne-C, Ar-A, Kr-B

Answer

Answer: C ✓ checked by 4AB · confidence high

Explanation

The heaviest gas, Kr, has the sharpest, lowest-speed peak (A), and the lightest, Ne, the broadest (C): Ne-C, Ar-B, Kr-A (c).
