Why do solids not affect equilibrium in a chemical reaction?
Solids do not affect equilibrium in a chemical reaction because their concentration remains constant and does not change during the reaction. This means that the presence of solids does not impact the equilibrium position or the rate of the reaction.
How do solids affect equilibrium in a chemical reaction?
Solids do not affect the equilibrium of a chemical reaction because their concentration remains constant and does not change during the reaction. Only the concentrations of gases and dissolved substances in a reaction mixture can affect the equilibrium position.
Why don't solids and liquids affect equilibrium in a chemical reaction?
Solids and liquids do not affect equilibrium in a chemical reaction because their concentrations remain constant during the reaction. This is because the amount of solid or liquid present does not change as the reaction progresses, so they do not impact the equilibrium concentrations of the reactants and products. Only the concentrations of gases and aqueous solutions can affect the equilibrium of a chemical reaction.
How can a chemical equation be used to write a equilibrium-constant expression?
Law of mass action (also called 'Law of Guldberg & Waage')Generalized reaction equation (cf. Note): aA + bB pP + qQAccording to the Law of mass action:Equilibrium constant (K>/) and backward (
Diffusing molecules move until they are?
Diffusing molecules never stop moving. In fact, no particle (atom, molecule) ever stops moving. All particles are in constant random motion, but in solids they just vibrate.
Which species are left out from the Keq expression?
The substances left out from the equilibrium constant expression (Keq) are usually pure solids, pure liquids, and solvents. These do not affect the equilibrium position because their concentrations remain constant. Only species that are present in aqueous or gaseous form and participate in the reaction are included in the Keq expression.

Why are solids and liquids not included in equilibrium expressions?
Because in comparison to the gases present they have insignificant volume. The basis of the equation for Kcis the molar volume concentration. For solids or liquids, this will be very close to zero, so it is not included.
What are two solids whose corresponding sides have a constant ratio?
The corresponding sides of similar solids have a constant ratio.
Solids and liquids are excluded from equilibrium expressions because?
They are just the medium in which the equilibrium takes place. It could be similar to boys and girls dating in a disco. The boys and girls (ions) interaction is different to the disco (liquid) that is allowing the interaction to take place, but is not interfering with it.
What is an material?
One that is in the solid state but does not have regularly ordered atomic structure, as do all elemental solids and pure compound solids at thermodynamic equilibrium.
Which type of motion is associated with solids?
Solids typically exhibit vibrational motion, where atoms or molecules within the solid vibrate or oscillate around their equilibrium positions. This motion contributes to the rigidity and shape of solids.
Why is cp used for solids instead of cv in heat transfer?
Specific heat capacity at constant pressure (cp) is used for gases because the heat transfer is generally at constant pressure conditions. For solids, heat transfer typically occurs at constant volume since solids do not easily change their volume. Therefore, the specific heat capacity at constant volume (cv) is used for solids in heat transfer calculations.
Why can't solids dissolve in water?
Some solid materials don't dissolve. When their cohesive bonds are stronger than the solvent's adhesive bonds, the former stays monolithic or becomes precipitate. Whether this happens depends on the equilibrium constant between the two media and their bound state, which further depends on their affinities, concentration, temperature, and pressure. A material with a small equilibrium constant may dissolve microscopically until its solution's reverse rate is equal.
