Homework Help: chemistry

Posted by jayla on Wednesday, March 14, 2012 at 12:29pm.

A study of the system, H2(g) + I2(g) == 2 HI(g), was carried
out. Kc = 54.9 at 699.0 K (Kelvin) for this reaction. A system was charged with 2.50 moles of HI in a 5.00 liter vessel as the only component initially. The system was brought up to 699.0 K and allowed to reach equilibrium. How many moles of H2 should there be in the container at that time?
