Consider the rxn during the Haber Process:
N2 + 3H2 > 2NH3
The equilibrium constant is 3.9 x 10^(5) at 300 K and 1.2 x 10^(1) at 500 K.
Find Delta H reaction and Delta S for reaction

Won't the van't Hoff equation allow you to calculate dHo?
Then use K to calculate dGo = RTlnK, and use that for dGo = dHTdS to calculate dS. 
The solubility of AgCl(s) in water at 25 C is 1.33x10^5 M and its deltaH of solution is 65.7 kJ/mol .
What is its solubility at 60.1 C ?
Please explain how to solve for this!!
