Question 1

Consider the reaction:

    2SO₂(g) 2SO₃(g)

for which ΔH° = –200. kJ and ΔS° = –186.5 J/K at 25°C. Assuming that ΔH° and ΔS° are independent of temperature, calculate the temperature where K_p = 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°	S°
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

​

CalculateΔS°for 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
