Calculate the ΔH°, ΔS°, and ΔG° at 298 K for the following reaction: (Use the values found in Thermodynamic Properties to calculate your answers for questions a and b.)
Al2O3(s) + 3 C(graphite) + 3 Cl2(g) → 2 AlCl3(s) + 3 CO(g)
a) ΔH° WebAssign will check your answer for the correct number of significant figures.
-64

Correct: Your answer is correct.
kJ/mol
b) ΔS° WebAssign will check your answer for the correct number of significant figures.
76.9

Correct: Your answer is correct.
J/K·mol
c) ΔG° WebAssign will check your answer for the correct number of significant figures.
-87

Correct: Your answer is correct.
kJ/mol (Determine from the temperature, ΔH and ΔS)
(d) Is the reaction extensive at standard conditions and 298 K?
Yes
NO
Correct: Your answer is correct.

(e) Write the expression for K.
(Format example: Kp = pHCl2 / pH2 . pCl2 would be entered as K_{p} = pHCl^{2}/pH_{2} . pCl_{2}.)

(f) Calculate the value of K at 298 K
(Please answer to 3 significant figures.)

(g) Estimate the value of K at 600 K.
(Please answer to 3 significant figures.)
