1.02 moles of the gas is present in the sample.
The conditions in which the gases deviate from ideal behavior is high pressure and low temperatures.
Correct option is 2.
Explanation:
Data given:
volume of the gas = 31.2 litres
temperature of the gas = 28 degrees or 301.15 K
pressure of the gas = 82.6 kPa or 0.815 atm
R (Gas constant) = 0.0820 Latm/moles K
number of moles =?
From the ideal gas law, we have
PV = nRT
rearranging the equation:
n =
n =
n = 1.02 moles
At high pressure and low temperature an ideal gas deviates from ideal behaviour. Under high pressure the gas molecules get closer to each other and intermolecular force acts on them as molecules attract each other while in ideal case gas has no attractions in its molecules.
Answer:
On the attached picture.
Explanation:
Hello,
At first, it is important to remember that kinetic molecular theory help us understand how the molecules of a gas behave in terms of motion. In such a way, the relative velocity of a gas molecule has the following relationship with the gas' molar mass:
∝
That is, an inversely proportional relationship which allows us to infer that the bigger the molecule the slower it. In this manner, as argon is smaller than xenon, it will move faster.
Now, as the gases are in equal molar amounts and considering that argon moves faster, on the attached picture you will find the suitable depiction of the gas sample, since red dots (argon) have a larger tail than the blue dots (xenon).
Best regards.
