Question

1. Consider the following at 25o C. SHOW ALL STEPS IN WORK

a. Complete and balance: CaO(s) + HNO3(aq)

b. Calculate change in Ho for the reaction in part a.

c. Calculate change in So for the reaction in part a.

d. Show how you would calculate change inGo for the reaction in part a. Plug all of the numbers into the appropriate equation, explicitly using the values you would plug into a calculator, if you had one available.

e. Predict the spontaneity of the reaction in part a. Briefly explain your reasoning.

f. Calculate the equilibrium constant using the data you calculated above. Is K greater than or less than one? Did you expect this value? Why or why not?
