Heterogeneous and homogeneous equilibria

Postby Peter Nguyen 2I » Sat Jan 12, 2019 6:27 pm

How are heterogeneous and homogeneous equilibria related to what we are learning?

Is heterogenous equilibria just a reaction at equilibrium that involves more than 1 phase?

Yes homogeneous equilibrium just means that all of the reactants and products are in the same phase, whereas in heterogeneous equilibrium, they are not. This is usually only relevant when calculating K, as if one of the products or reactants is a solid or liquid, its concentration would not be used.

if its heterogeneous with solid and a liquid in the balanced equation we wouldn't include them in our calculations for K and Q

Heterogeneous equilibrium is when there are different states of matter present in the reaction and homogeneous equilibrium is when all the states are the same.

Homogeneous equilibria is where all reactants and products are in the same phase. Therefore if they are all gasses all of the components would be incorporated in the equilibrium constant equation. Heterogeneous equilibria is when one or more of the reactants or products are in a different phase. If there is a reactant that is a solid or liquid and all other components are gasses it would be heterogeneous and that reactant that is a solid or liquid would not be incorporated in the equilibrium constant equation.

We have to keep in mind if any of the reactants or products are solids or liquids because we don't factor them in when we calculate the equilibrium constant, K.

Heterogeneous equilibrium is where different states of matter are present within a reaction and homogeneous means that there are no different states, everything is that same.

In heterogenous equilibria, some of the components are in different phases (solids, gases, etc.) while in homogenous equilibria the components are all in the same phase.
