An ICE table shows the initial, change, and equilibrium concentration values for a reaction at equilibrium. To solve it, you would need to find the equilibrium expression K for the reaction and the starting/ending values of the initial or end concentrations. To solve for the unknown, plug the known and unknown variables into the equilibrium expression K and solve using algebra.
To add on from the previous reply, an ICE table basically lays out the initial concentration, the change it endures, followed by the equilibrium concentration amount afterward. You start off by writing out the table and then inputting what's given in the problem into its respective spots. From then, you can then use what you know (e.g. if there isn't any product initially and then at the equilibrium constant has something, then you know that in the change, there must be some added amount). The way I remember it is initial + change = equilibrium, therefore ICE. Hope that helps!
Yes, and when using an ice table, make sure you check to make sure the equation you are looking at is balanced because the stoichiometric coefficients will play a role in the Change in concentration step. The coefficient will proceed the x term.
An ICE table is used for equilibrium concentrations when we are unsure of the amount of change (in molarity) in the reactants as the chemical reaction moves to equilibrium. I stands for initial, which are the molarities that are given. Sometimes, the problem will only provide the moles and the container volume, and you will have to convert into molarity. C stands for change, which is the change that each reactant and product goes through as the reaction goes to equilibrium. Most people designate change as x, with a coefficient in front depending on the molar ratio (from the chemical equation). E stands for equilibrium, which is the concentration of the molecules at equilibrium. This is the addition of the I and C for each molecule. After that, you would use Kc in order to calculate the actual change (x).
ICE tables are used when you need to find out the equilibrium concentrations of products or reactants when only given the initial concentration of one. You use the balanced chemical equation when calculating the change (represented by x times the stoichiometric coefficient) and then solve for x to find out how much of the reactants and products are present at equilibrium.
You use an ice table to calculate the concentrations of all molecules in a reaction at equilibrium. You set up the table with Initial, Change, Equilibrium going vertical and the molecules involved in the equilibrium constant going horizontally. You list the initials, the changes, and then the equilibrium is either the initial - the change or the initial + the change. You can then use these "concentrations" to calculate what x is & calculate the actual concentration of reactants.
