4. More on Concentration Units: The mixing ratio of ozone at the surface (x_(O_(3))^(0km)) is about 40.0 ppb, and in the mid-stratosphere (x_(O_(3))^(30km)) is 8.3 ppm, where the total pressure is 11.5 mbar. Calculate i) the partial pressure of ozone, and ii) the number density (C) (in molec/cm^3) of ozone at both altitudes. (assume T=0°C)

6. CHEM 109 review warning: Principles of Chemical Reactivity: Fill in the blanks.
a) A "product favored reaction" (i.e., one that "goes") has a ΔG that is (+ or -), and a K_eq value that is (>, <, or equal to) one.
b) A "reactant favored reaction" (i.e., one that does not "go") has a ΔG that is (+ or -), and a K_eq value that is (>, <, or equal to) one.
