Calculating an Equilibrium Constant from .
The standard free-energy change for the Haber process at 25 °C was obtained in Sample Exercise 19.9 for the Haber reaction:
= -33.3 kJ/mol = -33,300 J/mol
Use this value of to calculate the equilibrium constant for the process at 25 °C.
The Ksp for a very insoluble salt is at 298 K. What is for the dissolution of the salt in water? (a) -265 kJ/mol. (b) -115 kJ/mol. (c) -2.61 kJ/mol. (d) +115 kJ/mol. (e) +265 kJ/mol.
