Fugacity of a component in an ideal gas mixture is euqal to the partial pressure of that component in the mixture. The fugacity of each component in a stable homogeneous solution at contant pressure and temperature __________ as its mole fraction increases.
Answer & Solution
Correct Answer:
Option
C
We know for an ideal binary solution by Lewis-Randall rule fugacity of a component is directly proportional to mole fraction of that component. So basically on increasing the mole fraction the fugacity of the component is increasing but this equation is valid only for an ideal solution but, we can extend this behavior for real solution also under some conditions.
