Question

How can define formul a for real gas

Answer 1

Helloo!

We can define formula of real gas with as formula of real gas is same as Vanderwalls...

The vanderWaals equation is:

[P + (n2a/V2)](V - nb) = nRT

Where:

P - pressure,

V - volume,

n - number of moles,

T - temperature,

R -  Gas constant and the value of R is 0.0821

a and b - constants, which are chosen to fit experiment as closely as possible to individual gas molecule.


hope it helps

Answer 2

Real gas:- A gas which doesn't follow ideal gas behaviour that is obeying all gas laws at any temperature and pressure is called as real gas.

Special Points:-

*Real gases have a very low pressure.

*These gases have high temperature.

*On considering the compressibility factor(z),

The compressibility factor (z) is ;

Z = PV/nRT

So For real gas, z≠1

So, PV≠nRT.
