Homework Help: Chemistry Problem

Posted by Peter on Friday, March 8, 2013 at 10:29pm.

At 25 oC, Kc = 0.145 for the following reaction in the solvent CCl4.
2BrCl <----> Br2 + Cl2

A solution was prepared with the following initial concentrations: [BrCl] = 0.0482 M, [Br2]= 0.0307 M, and [Cl2]= 0.0277 M.

What will their equilibrium concentrations be?
How do i know when the change in concentration is +x or -x?

I tried-2BrCl<-->Br2 Cl2

.0482 .0307 .0277
-2x +x +x

and reverse too but it's wrong. Any ideas?
