Calculate equilibrium concentraion of NO2(g)

[decibel]

i have 2 questions, i just don't seem to get , here it goes

at 25 degrees, kc = 1.6 x 10^-17 for the reaction

N2(subscript) (g) + 2O2(subscript)(g) ---- 2NO2(subscript)(g)

concentration of N2 = .0320 mol^-1
concentraion of O2 = .00860 molL^-1

calculate equilibrium concentraion of NO2(g)


the second question is :

for the following rxn

2SOsubscript2 (g) + Osubscrupt2(g) ---- 2SOsucript3 (g)

calculate valua of kc if 4 mol of SO3 is placed in a 2L container and allowed to reach equil.

equililbrium concentration of O2 = .500 mol/L^-1

can someone help please?

my answer for kc was 1 for the 2nd question , can anyone verify that?

I'm no expert in Chemistry, but I can say that there aren't many chemists on these boards. Maybe you should try posting on the Chemistry boards if you have not already.

HW policy is that you take at least a blind swing at the problem.

"One" looks good for Q2.

i did take a swing at them both, that's why I am posting them here :D...but nvm now i got them right thanks for "attempting" to help everyone haha
