the reaction between H2 and O2 reaches equilibrium in a closed container according to the following balanced equation:
the volume of the container is 5dm3
calculate the equilibrium constant (Kc) for this reactin
You can do this with no other information? I don't think so. However, that isn't the only problem. You have a problem involving H2 and O2 but your equation involves HCl and O2.
You need to read your post after posting to make sure you didn't aggregate problems.
