A student determines that an aqueous solution that contains 0.262 M sodium formate and 0.238 M formic acid, also has an H3O+ concentration of 1.98x10-4 M. Based on these data, calculate the value of the equilibrium constant K for the equilibrium: HCOOH(aq) + H2O=H3O+(aq) + HCOO-(aq) Calculate K as is usually done, omitting the solvent, water, from the expression for K: K=
Dinitrogen tetraoxide is a colorless gas that dissociates into nitrogen dioxide, a reddish brown gas. N₂O4 (g) 2 NO₂ (g) An experiment was run to demonstrate that this is a dynamic equilibrium. Starting with a special form of N₂04 where one of the oxygens was isotopically labeled (180 instead of 160), the system was then allowed to reach equilibrium. 18 N-N If the equilibrium is NOT dynamic the forward reaction would simply run until equilibrium is reached and then cease. Under this condition which of the structures below would be observed for N₂O4? If the equilibrium IS dynamic the forward and reverse reactions run even after equilibrium is reached. Under this condition which of the structures below would be observed for N₂04 ? 10
of the equilibrium is NOT dynamic the forward reaction would simply run until equilibrium is reached and then cease. Under this condition which of the structures below would be observed for N₂O4 ? If the equilibrium IS dynamic the forward and reverse reactions run even after equilibrium is reached. Under this condition which of the structures below would be observed for N₂O4 ?
