Question- What is the ?Grxn of the reaction below at 25C when [NO2-]=[H3O+]=1x10^-5 M and [HNO2] = 1M? Will the reaction be spontaneous or non-spontaneous?
HNO2(aq)+H2O(l) --> H3O+(aq) + NO2-(aq)
I got 57.05KJ/mol however this is not the answer. I used ?G = -RT ln(k). Did I use the incorrect equation?
The answer was -38.5 kJ/mol, spontaneous. What might have perhaps gone wrong?

A 0.468 mol of O2 gas has a volume of 11.5 L at a certain temperature and pressure. If all this O2 were converted to ozone (O3) at the same temperature and pressure, what would be the volume of the ozone. 3O2?2O3
Draw the Lewis structure of the major resonance form of the thiosulfate ion, S2O3 2-. Include all lone pairs of electrons. Include formal charges on atoms with charges.
Rb-87 decays with a half-life of 48.8 billion years to Sr-87. For short periods of time, there are so few decays that the number of changed nuclei is far smaller than the experimental error. The current limit on object ages therefore is 100,000,00..
