Homework Help: Chemistry --really need help!

Posted by Angelica on Friday, February 19, 2010 at 7:05pm.

I am really struggling with these problems!!

A reaction mixture that consisted of 0.20 mol N2 and 0.20 mol H2 was introduced into a 25.0 L reactor and heated. At equilibrium, 5.0% of the nitrogen gas has reacted. What is the value of the equilibrium constant Kc for the reaction below at this temperature?

N2 + 3H2 <--> 2NH3

I don't know how to approach it because Im' not sure how to factor in the 5% of N2 that reacted. I found the molarities of the reactants..and i know the Kc equation I just don't know how to set it up...someone please help!!
