Title: equilibrium
Post by: wadi on April 09, 2006, 08:57:40 PM

this equilibrium problems drive me ..please help.
A certain quantity of HI is introduced to a 1.0 l reaction vessel at a certain temperature
 H2 (g) + I2 (g) <==> 2HI (g)
When equilibrium is reached there are 2.5 moles of I2 present. How many moles of Hi were introduced orginally? ???

Do you know the equilibrium constant for the reaction?
