ICE Tables

Initial, Change, Equilibrium. The whole method rests on one idea: the change column follows the mole ratio, so one known change gives you all the others. This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.

the one idea

why this one carries the topic.

Keq is where a reaction settles, written as one number. Big K, products win; tiny K, barely started; and no amount of waiting changes it. Set up the expression, feed it an ICE table, and you can predict the mixture before you ever open the flask.

ICE tables track Initial concentrations, Change in concentrations using stoichiometric ratios, and final Equilibrium concentrations for calculating equilibrium constants.

what examiners catch — Students fail to apply stoichiometric ratios in the change row or forget that changes are negative for reactants and positive for products.
what you leave with

four things, not forty.

what's underneath

nothing here is a standalone fact.

knowhere maps every concept to what it rests on and what rests on it — 2 underneath this one, 0 built on top. Each one says why, in a sentence, not as an arrow on a diagram.
