Answer:
Following are the solution to this question:
Explanation:
Please find the complete question in the attached file.
In point a:
When some water evaporates from its mixture, then when a thick layer is initiated, it reduces salt solubility, but sodium remains unclear throughout the solution (ppt solte).
In point b:
Ksp is measured by calculating the mass of its solvent reduction process, decreasing salt solubility and hence decreasing Ksp.
In point c:
From of the graph [tex]\Delta \ H \ \ or \ \ \Delta \ S[/tex] are calculated by [tex]\frac{1}{T}[/tex] v/s lnKsp
(decrease) LnKsp may shift,
[tex]\Delta \ H = -slope \times R \\\\\Delta \ S = intercept \times R[/tex]
So, both are decreasing
