Problem: Consider the following samples of gases:If the three samples are all at the same temperature, rank them with respect to partial pressure of helium (PHe).

FREE Expert Solution

Recall that the partial pressure of a gas (PGas) in a mixture is given by:


Pgas=χgasPtotal


where: 

χGas = mole fraction of the gas

Ptotal = total pressure of the gas mixture
