The Effects of Pressure and Volume on Equilibrium (15.3.3) Flashcards
• A change in total pressure that does not affect the partial pressures of the components of a system does not apply a stress, and therefore does not affect the equilibrium.
• A change in total pressure that does not affect the partial pressures of the components of a system does not apply a stress, and therefore does not affect the equilibrium.
• A change in the volume of a system affects the partial pressures or concentrations of the components of the system; therefore, the system will respond to counteract
the stress.
• A change in the volume of a system affects the partial pressures or concentrations of the components of the system; therefore, the system will respond to counteract
the stress.
• If the sum of the stoichiometric coefficients of the products of a balanced chemical reaction equals the sum of the stoichiometric coefficients of the reactants, the system cannot respond to a change in volume.
• If the sum of the stoichiometric coefficients of the products of a balanced chemical reaction equals the sum of the stoichiometric coefficients of the reactants, the
system cannot respond to a change in volume.
