Kc=5.85x10^-3 at 25 degrees C for the reaction N2O4(g)<-->2NO2(g) fifteen(15.0) grams of N2O4 is confined in a 5.00-L flask at 25 degrees C. Calculate(a) the number of moles of NO2 present at equilibrium and(b) the percentage of the original N2O4 that is dissociated.
c. progress....the other 3 are complete antonyms

i keep getting 32.3005 for T, if you have worked it out did you use 8.314472 for R, also is -126kj/mol -12600j/mol?
The aquation of tris(1, 10-phenanthroline)iron(II) in acid solution takes place according to the equation: Fe(phen)3^2+ + 3H3O + 3H2O==> (Fe(H2O)6^2+ + 3 phenH^+ If the activation energy is 126 kJ/mol and frequency factor is 8.62 x 1017 s-1, at what temperature is the rate ...
i dont understand where k1 k2 t1 t2 come from... :(
doesnt vq = - work ?...signs are important since work = -u, and u = vq
