In the upper atmosphere, ozone is produced from oxygen gas in the following reaction. Calculate ΔHo for this reaction.
3 O2(g) --> 2 O3(g)
285
Calculate ΔSo for ozone formation.
-141
Calculate ΔGo for ozone formation.
326
Assume an atmosphere where p(O2) = 0.180 atm, and where T = 298 K. Below what pressure of O3 will ozone production be spontaneous? (Enter your answer in atm).
This is the one i don't get how to do, i know that you Use the formula DeltaG=DeltaGo + RTlnQ for this reaction but i don't exactly know how to use it.
Another question was A galvanic cell is constructed with a silver-silver chloride electrode, and a nickel strip immersed in a beaker containing 4.65x 10-2 M solution of NiCl2. Determine the balanced cell reaction and calculate the potential of the cell. Enter in volts. (assume a temperature of 25oC)
I know that you figure the correct stoichiometry for the reaction first that NiCl2 --> Ni2+ + 2 Cl-). Then plug into nerst equation but how. Thanks for anyone who can *delete me*
