CHE180 - General College Chemistry II
Assignment 8-2 - Enthalpies of Formation
Instructions: This exercise is due at class time on Monday, February 14, 2022.
1. Lime (CaO) is made by heating limestone in a kiln at 900°C. Using enthalpies of
formation, TABLE 8.3, p. 203, Masterton/Hurley, calculate AH for the reaction:
I CACO, (s) --->(CaO (s) +1CO2 (g)
- GI5.ley-373.5 aynd
-1206.9 Ky
3.
rodudt -
reschents
: (1(-635.) +1(-3955))-(1(-12069)
: (- 1028.6) -(-1264.9)
AH = 178.3 K/mal
2. Estimate the quantity of energy (in kJ) needed to manufacture 1.00 metric tons of lime
via the reaction in (1).
3. What quantity of coal must be burned to supply the energy in (2), assuming that the only
combustion reaction is: C(s) + 02 ---> CO2 (g)?
4. Given the reaction below, calculate AHf for the sulfite (SO,²') ion.
SO,? (aq)+ 2H (aq) + 2NO3 (aq) ----> SO,2 (aq)+ 2NO2 (g)+ HaO (1) AH=-88.0 kJ
