Q237

In a homogeneous solution, the activity co-efficient of a component depends upon the

A.
Pressure
B.
Composition
C.
Temperature
D.
All of the above
Answer

Answer: Option D

Solution

Answer: Option D
Solution:
Activity co-efficient is defined as the ratio of fugacity at existing conditions to fugacity in ideal solution. Since fugacity is a function of temperature, pressure and composition we can say activity co-efficient is also a function of temperature pressure and composition.
