### When to do ice tables

How do we know when to use an ICE table to find the composition of the mixture, or when we have to use only the K=[products]/[reactants] equation? Is it dependent on whether initial concentrations or equilibrium concentrations are given?

If the questions provides you with initial concentrations and asks you to solve for the equilibrium compositions you should use the ICE table.

You should also make sure you have the equilibrium constant in order to solve the ice table. You then use the K=[Products]/[Reactants] equation to solve for x and find the equilibrium concentrations.

Yes! What you decide to do in order to solve what is asked is dependent on the information given. Usually, you make an ice table when it is asked to find the resulting concentrations of the reactants and/or products at equilibrium. Using the equation for k can be another way to solve for the resulting concentrations of the reactants and/or products at equilibrium (often if the product and/or reactant equilibrium concentrations are not given).

A hint to do an ICE might be when you get only a few concentrations and you get K
