Write down the equation for the lewis-randall rule for fugacity of species in an ideal solution.

Answer :

Lewis-Randall rule : Lewis-Randall rule states that, the fugacity of a component is directly proportional to the mole fraction of the component in the solution in an ideal solution.

The equation used for the Lewis-Randall rule for fugacity of species in an ideal solution is :

where,

= fugacity in the solution

= fugacity of a pure component

= mole fraction of component
