K

Definition

In this context, K refers to the equilibrium constant, which is a numerical value that expresses the extent to which reactants are converted into products at equilibrium for a given chemical reaction equation.

Analogy

Imagine K as a scale that measures how balanced or unbalanced a seesaw is. If K has a small value, it means there are fewer products compared to reactants and the seesaw is tilted towards the reactants side. If K has a large value, it means there are more products compared to reactants and the seesaw is tilted towards the products side.

Related terms

Le Chatelier's Principle: A principle stating that when stressors are applied to an equilibrium system, such as changes in concentration, pressure, or temperature, the system will shift in order to minimize those stresses.

Q (Reaction Quotient): Similar conceptually to K but calculated using concentrations or partial pressures of reactants and products at any point during a reaction rather than solely at equilibrium.

Equilibrium Expression: Mathematical representation of an equilibrium reaction using concentrations or partial pressures of reactants and products.
