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 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°
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

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.

Fatal fungal infections may be able to resist newer antifungal drugs. Globally, fungal infections are often fatal due to the lack of access to multiple antifungals, which may be required to be utilized in combination. Single antifungals may not be enough to stop a fungal infection from causing the death of a patient.

All patients with hyperparathyroidism will develop osteoporosis. The parathyroid glands maintain blood calcium within the normal range. All patients with this disease will continue to lose calcium from their bones every day, and there is no way to prevent the development of osteoporosis as a result.

The use of salicylates dates back 2,500 years to Hippocrates's recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.
