thermodynamics

Step 1

Fugacity is used in case of real gas in place of pressure.

It denotes interaction between molecules of real gas.

It has same unit as of pressure.

Step 2

Lewis- Randall rule is applicable only for ideal solutions.

Lewis-Randall rule states that fugacity of component i in the ideal solution is directly proportional to its mole fraction which is shown below:

Where f_{i} is proportionality constant

Step 3

The Lewis- Randall rule for the fugacity of component i in a gas mixture is an approximation is giv...
