Question

Suppose you had 1.0 mol samples the following gases at STP. If the volume of each of the samples of gas was reduced to one tenth of its original size and the temperature remained the same, which gas would have the lowest pressure?

A) He
B)Kr
C)N2
D)NO
E)O2

Answer 1

A.He
because He 's molecular weight is small than each other

Answer 2

A) He

Step-by-step explanation:

Hello,

In this case, as the volume is dwindled and the pressure is increased 10 times the initial one, an increase in the non-ideality of the mixture is shown, thus, the least nonideal gas is the helium since it has the weakest intermolecular forces causing its pressure to be the lowest one.

Best regards.
