The compressibility factor for `H_2` and He is usually

A

`Zgt1`

B

`Z=1`

C

`Zlt1`

D

Either of these

Text Solution

Verified by Experts

The correct Answer is:

A

Since for `H_(2)` and He, PV > nRT and Z=`(PV)/(nRT)`. Hence Z is more than 1

The compressibility factor for an ideal gas is

Assertion: The compressibility factor for H_(2) and He is [1+(bP)/(RT)] Reason: The compressibility factor H_(2) and He can be derived from van der Waal's equation.

The compressibility factor for an ideal gas is .

The compressibility factor (Z) of real gas is usually less than 1 at low temperature and low pressure because

At a high pressure, the compressibility factor (Z) of a real gas is usually greater than one. This can be explained from van der Waals equation by neglecting the value of:

The compressibility factor of H_(2)(g) at its critical condition if it follows van der Waals' equation is given by:
