Скачать или смотреть ICE chart (table) basics

In this video, I explain how to use an ice chart to calculate the equilibrium concentration of a reversible reaction. Things to remember:

-If one or more of the species is a pure liquid, solid, or a solvent in excess, it does not appear in the equilibrium constant expression (K=[products]/[Reactants]). As far as the ICE chart goes, the values for that species are all zero, but this DOES NOT mean that the concentration is zero (making K automatically zero or infinity). The concentrations are actually equal to 1, so therefore they don't add anything to the equilibrium expression (something multiplied by 1 is just that something...) and its easier to just omit them.

-In most cases, you can just use Le Chatelier's principle and tell based on the different concentrations of each species whether the reaction is going to go in the forward or reverse direction. When in doubt, just calculate the reaction quotient (Q)

Practice!!!

I hope that this video helps you, and as always thanks for watching!!
