a. write a k expression for this reaction (note that that liquid water shouldn’t be included in the k expression).
b. use the k expression and equilibrium concentrations on the left to determine the k value at 25 deg c. show all work for full credits.
c. what is the equilibrium constant k’ 65 degrees c?
d. compare the k’ constants; are the value difference agree or against with endo or exothermic determination?
