Question 1

On the average, air contains about 9.3 mL of argon per liter. What would be the partial pressure of argon in air when the barometric pressure is 780 Torr?
◦ 84 Torr
◦ 7.3 Torr
◦ 780 Torr
◦ 770 Torr
◦ 790 Torr

Question 2

One of the natural processes that destroys ozone in the atmosphere is postulated to consist of two steps:

O3(g) + UV radiation → O2(g) + O(g)
O3(g) + O(g) → 2 O2(g)

The standard enthalpies of formation for ozone and for atomic oxygen are +142.7 kJ/mol and +249.2 kJ/mol, respectively. What would be the standard energy change associated with the combination of ozone and atomic oxygen to form 50.0 L of molecular oxygen, measured at -75 °C and 0.12 atm?
◦ -38 kJ
◦ -72 kJ
◦ -150 kJ
◦ -196 kJ
◦ -600 kJ

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.
