Why is the mole ratio a whole number?
The mole ratio is a whole number because it represents the proportional relationship between the amounts of reactants and products in a chemical reaction, based on the coefficients in a balanced equation. These coefficients indicate the simplest whole number ratio of moles required for the reaction to occur. Using whole numbers ensures that the quantities of substances used or produced are practical and measurable in real-world scenarios. Additionally, it reflects the conservation of mass, as atoms are neither created nor destroyed during a chemical reaction.
What is the equilibrium constant of aA plus bB equals cC plus dD?
The equilibrium constant (K) for the reaction aA + bB ⇌ cC + dD is expressed as K = [C]^c [D]^d / [A]^a [B]^b, where square brackets denote the concentrations of the respective species at equilibrium. The coefficients a, b, c, and d correspond to the stoichiometric coefficients of the reactants and products in the balanced chemical equation. The equilibrium constant provides insight into the extent of the reaction and the relative concentrations of reactants and products at equilibrium.
