Question 1

Consider the reaction:

    2SO2(g) 2SO3(g)

for which Δ = –200. kJ and Δ = –186.5 J/K at 25°C. Assuming that Δ and Δ are independent of temperature, calculate the temperature where Kp = 1.


972. K
2072 K
200. K
1072 K
None of these are correct.

Question 2

Consider the reaction
2N2O5(g) 4NO2(g) + O2(g)
at 25°C for which the following data are relevant:
 
ΔHf°
N2O5
13.30 kJ/mol
355.7 J/K·mol
NO2
33.15 kJ/mol
239.9 J/K·mol
O2
0 kJ/mol
204.8 J/K·mol

CalculateΔfor the reaction.

Reference: Ref 17-4


808.7 J/K
89.0 J/K
453.0 J/K
-266.7 J/K
1164.4 J/K
