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
Correct Answer: All of the above
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.
