### ICE Table

Using the ICE tables, how do you know when the change in molar concentration is positive or negative?

If there is initially no products, then the change for the products must be positive. If the products side is positive, then the reactant side must have a negative change and the same is for vice versa.

Usually the products have a positive change since there are more products being created and the reactants have a negative change since reactants are being used to make products.

If the forward reaction is favored, then reactants will have a negative change and products will have a negative change, and vice versa when the reverse reaction is favored

What is an ICE table?

An ICE table is used to calculate the concentrations of substances when not given all the equilibrium concentrations. We use the Kc and set it equal to the ratio of concentrations. The ICE table tracks the initial, change, and final concentrations of the equilibrium concentrations.

Change in molar concentration is usually positive on the product side because product are being created from the reactants. This means that the reactants must have a negative change in concentration.

ICE tables are composed of the concentrations of molecules in solution in different stages of a reaction, and are usually used to calculate the K of a reaction.

ICE table is the table we learned in class with (I)nitial molar concentration, (C)hange in molar concentration, and (E)quilibrium Molar Concentration. We later used the quadratic formula, and simplified cubic equations to solve for K and X to find the molar concentrations.

You should calculate Q so you know which direction the reaction is moving and then you can identify if the products or reactants are favored to determine if x is positive or negative for each molecule
