gen chem
yes, I figured that one out. Thanks so much for the help!

gen chem
2NO <-> N2 O2 initial .116 0 0 change -x +x +x equil .116-x x x

gen chem
yes I did, but im still not getting the right answer. I got .1136 which is not the correct answer.

gen chem
At 2273K, equilibrium constant for the reaction 2NO(g)<->N2(g)+O2(g) Kc=2.4x10^3 What would be equilibrim concentration of N2, if initial concentration of NO was 0.1160M?

gen chem
yes, it wants an actual value

gen chem
what would Qc be if the pressure of the container decreased by a factor of 2.417 for the following reaction? 4Hcl(g)+O2(g)<-->2Cl2(g)+2H2O(g) Kc=13.298 @ 753K

gen hem
what is the free energy change in kJ for the reaction below? 2NO3-(aq)+8H+(aq)+3Hg(l) <-->2NO(g)+4H2O(l)+3Hg2+(aq) E0=0.106V

gen chem
i tried that, apparently its not the right answer either =/.

gen chem
with n=10, im getting an answer of 0 when I do e^(k) i got lnK= (10)(96485)(-1.133)/(8.314)(298) lnK=-441.228 e^(-441.228)=0

gen chem
what is "n" and thank you so much for all the help!
