Homework Help: chemistry

Posted by Andy on Monday, May 10, 2010 at 7:32pm.

Can you please check if I came up with the right answer for this please.
A 4.30L container had 55.10 moles of N2O4 added to it. When equilibrium was established the concentration of N2O4 was found to be 1.69M.What is the Kc for the following reaction?
N2O4(g)<-->2NO2(g)

Reasoning and workings:
N2O4<-->2No2
12.814M of O
12.814-x2x
12.814-x=1.69
x=11.124M
Kc=[NO2]^2/[N2o4]
=22.248^2/1.69
=292.88M
Hows that ??
Is it right??
If it is i am going to be so happy!!
Thanks andy
