### Calculating Equilibrium Composition

Posted:

**Wed Nov 22, 2017 6:03 pm**Today in lecture we discussed how one would calculate equilibrium concentrations using x in the ICE box when the change in concentration is unknown. The example given had one negative and one positive value, and professor also addressed that one value would be too large if both were positive. When calculating for composition of an equilibrium mixture, is it possible to receive two negative values? Thanks in advance!
