ICE charts
When we are trying to find the change in concentration, how do we know whether to add or subtract x?
Re: ICE charts
In an ICE chart, you normally add x to the products and subtract x from the reactants.

Re: ICE charts
When you change the concentration of something (let's say i reduce the amount of product), the reaction shifts to the right, causing a decrease (-x) of reactants and a (+x) in products. The same can be said for the other way around. It all depends on how the reaction changes.

Re: ICE charts
To add to the above answer....
If reaction favors products then the equilibrium will shift to the right (towards the products). You will then subtract x from the reactant side and add x on the product side.
If reaction favors the reactants then the equilibrium will shift to the left (towards the reactants). You will then subtract x from the product side and add x to the reactant side.
And like Robert said early, it all depends on how the reaction changes to figure out what whether to add or subtract x from the product or reactant side.

Re: ICE charts
So this is kind of an overview when filling out an ICE chart with X ...
Note that the equation will shift in only one direction. Then indicate an amount, x, that it shifts and write the stoichiometric coefficient in front of x and put a minus sign in front of any species for which the concentration decreases and use a plus sign in front of x of any species for which the concentration increases.
