CHEM 102 Lecture Notes - Lecture 16: Reagent, Partial Pressure, Dynamic Equilibrium
Document Summary
Describes the concentrations of the reactants and products in a reaction at equilibrium. Small k = high concentration of reactants. Rate of reverse reaction = the rate of the forward reaction the concentrations of reactants and products are not equal. Only the rate of forward and reverse reactions are equal. Equilibrium constant describes how far the reaction proceeds once we reach equilibrium. Given by the law of mass action (relation between the equation and the concentration of the products and reactants. The ratio is always the same reguardless of the initial concentration) Three modifications of equilibrium constant: reversing the reaction, multiplying coefficients by a factor, adding 2 or more individual equations. Partial pressure is proportional to the concentration in gaseous reactions. Ratio of the concentration of products raised to the stoichometric coefficients to to the concentrations of reactants raised to their stoichiometric coefficients at any point of the reaction.
