Finding initial concentration by using Kc and equilibrium concentration?!
At a certain temp the Kc for the Equillibrium reaction #H_2+ I_2 rightleftharpoons 2HI# is 51,50.
An unknown amount of HI was placed in a 1 dm^3 container. At equilibrium 0,218 mol of Hydrogen gas (H2) was present.
i)How much HI was originally placed in the container?
ii) How much I2 and HI were present at equilibrium?

Here's what I get.
Explanation:
This looks like the appropriate time to set up an ICE table.
The equilibrium concentration of
Our ICE table now becomes
We can now insert these numbers into the equilibrium constant expression.
The volume of the container was
