ICE Box Ratios

[Vana Mirzakhani 3I]

May someone please explain the ratios for the ice boxes that we do? How does "-x" work with ratios? Thank you.

What do you mean by ratios? As in Products/ Reactants? -x is how much product has been taken away.

-X is usually found in the "C" or the "change" row of the ICE table. It is not used when calculating K.

I'm not sure if this answers your question but if you mean ratios as in using the balanced equations then if the reaction is like A+B-->2C then on the products side of the ice table on the change line it would be -X and -X but for the products side it would be +2X. Hope that helped

For a majority of the ICE tables, "-x" will be located in the "C" or change row for the reactants, and "+x" will be located in the "C" row for the products. It is also important to remember to multiply "x" by the molar ration of that compound. For example, if 2 CO2 is one of your reactants, the change would be "-2x."

-x will always be on the reactant side, someone correct me if im wrong (:

[John_Richey_4A]

-x is just what you subtract from the initial.

[Arta Kasaeian 2C]

So the “x” usually comes to work when calculating the change the concentrations/pressures we don’t know the amounts of. The (-x) is applied to the reactants side, which means when you make the table i would draw a huge line between reactants and products and anything left of that line is negative.

basically think of it as x is negative for the reactants because these are being used up to form the positive products
