Stuck on one problem.

Consider the following gas samples:

Sample A Sample B
S2 (g) O2 (g)
n = 1 mol n = 2 mol
T = 800 K T = 400 K
P = 0.20 atm P = 0.40 atm

Which of the following statements is false?

(A) The volume of sample A is twice the volume of sample B.
(B) The avg KE of the molecules in sample A is twice the avg KE of the molecules in sample B.
(C) The fraction of molecules in sample A having a KE greater than some high fixed value is larger than the fraction of molecules in sample B having KE greater than that same high fixed value.
(D) The mean square velocity of molecules in asmple A is twice as large as the mean square velocity of molecules in sample B.
(E) Assuming identical IMF's in the two samples, sample A should be more nearly ideal than sample B.
