Activity co-efficient is a measure of the
Answer & Solution
Correct Answer:
Option
A
Activity coefficient \[{{\gamma }_{i}}=\frac{{{\overset\frown{{{f}_{l}}}}^{real}}}{\overset\frown{{{f}_{l}}^{ld}}}\]
For an ideal solution activity coefficient $$= 1$$
And for real solution it tells about the departure from ideal solution by real solution like compressibility factor in case of gases.
