Calculate the acetate ion concentration in a solution prepared by dissolving 1. In an experiment, 0. Calculate the relative molecular mass of the vapour. Chemical equilibrium A. Definition: the state in which the concentrations of all reactants and products remain constant with time.
Law of mass action equilibrium expressions 1. In equilibrium expressions: always include gases g and aqueous aq do not include solids s and pure liquids l 3. When the balanced equation for a reaction is multiplied by a factor of n, the new equilibrium constant is K n. Relationship between K and equilibrium: 1.
Large K values- equilibrium lies to the right favors the products 2. Small K values- equilibrium lies to the left favors the reactants D.
Calculations involving Kc, Kp, and Ksp 1. Kp: use when given pressures atm 3. Ksp: use when dealing with solid salts breaking apart into ions 4. Equilibrium Calculations A. If given equilibrium conditions- plug directly into the equilibrium expression B.
Reaction quotient Q 1. Used to determine if a system is at equilibrium, and if not, which direction the reaction will shift in order to establish equilibrium 2. Left towards reactants Right No change No change speeds up rxn in both directions Heat is in the products, increasing the temp is adding heat- shifts left Heat is in the reactants, increase the temp is adding heat to the reactants- shifts right Right Left Shifts from largest of moles of a gas to smalles Shifts from smallest to largest gaseous moles Solubility Product Ksp A.
The value of the constant identifies the degree to which the compound can dissociate in water. It is influenced by surroundings. A saturated solution is in a state of equilibrium between the dissolved, dissociated, undissolved solid, and the ionic compound. Austin State University with contributing authors. Introduction Recall that the definition of solubility is the maximum possible concentration of a solute in a solution at a given temperature and pressure.
Calculation of K sp from Equilibrium Concentrations We began the chapter with an informal discussion of how the mineral fluorite is formed.
