Entropy change of mixing two liquid substances depends upon the

A. Molar concentration

B. Quantity (i.e. number of moles)

C. Both A and B

D. Neither A nor B

Answer: Option C

Solution(By Examveda Team)

Since entropy change of mixing is $${\left( {\Delta s} \right)_{mix}} = - nR\sum {} {x_i}\ln {x_i}$$
So, it is dependent on both number of moles and composition as we can see physically also that more and more number of moles we add to the system the system behavior changes and the properties changes.
