Homework Statement


I just have a concept question on LCP.
in reaction: A(aq) + B(aq) <-> C(aq)
A is added and rxn is left to reach a new equilibrium.
Once @ new eqm, is [A] higher than before? and obviously [C] is lower, right?

I hope you will get to a point where the opposite is obvious.

"Changing the concentration of an ingredient will shift the equilibrium to the side that would reduce that change in concentration. The chemical system will attempt to partially oppose the change affected to the original state of equilibrium."

It will probably help if you can formulate the equations, equilibrium equations + conservation of mass and see what they tell you.
