Homework Help: Chem II

Posted by Ken on Wednesday, June 25, 2008 at 1:55pm.

For the reaction at 430 degree C, H2 + I2 <----->2HI. Kc = 54.3. Initially 0.714 moles of H2 and 0.984 moles of I2 and 0.886 molrd of HI are placed in a 2.40 L vessel. The equilibriuim concentration of H2 and I2 is _____.

This is what I did. I changed all the moles ot M. Then I subbed all the M's into an ICE chart, and then I subbed all of that information into the Kc formula, and then tried to work the quadradic equation, but nothing looks right with the answer, not to mention that none of them match up with the multiple choice answers.
