Do the coefficients you multiply x by in the ICE box always have to be the same as the stoichiometric coefficients? I think I remember it being briefly mentioned in the module but I didn't fully understand. For example if you have a reactant with a stoichiometric coefficient of 1 and a product with a stoichiometric coefficient of 2 could you say the change in molar concentration is 1/2x for the reactant and x for the product?
You could! As long as ratios match, its perfectly fine. I think the 1/2 might make solving for x a little more complicated because you square a decimal, but that's a matter of preference. Hope this helps!
It's easier to use whole numbers because you will usually end up with a quadratic equation already, and it's easier to calculate when you have as many whole numbers as possible. Theoretically though, you could, as long as you don't mind the decimals.
