chemical equlibirum

[Hawa Kamara 1F]

[This was a reply to one of my questions from before... let me know if you want me to explain more about my question]

so that would mean is the reactant side has a 2[H2]

then it would be .185M -2x or would it just stay as .185M -x?

If you are talking about finding the equilibrium constant, then It would be .185M -2x. 2x shows that there is 2x change since there is 2x amount of reactant(or product, don't know the specific question you are referring to). Hope this helps.

And additionally, when you use this value to solve for k or q, the stoichiometric coefficient also comes up again-- you would put the concentration into the equation as (0.185M-2x)² . Those are the two ways you'll have to use that coefficient.
