Concentrations of Solutions (Section)
(a) You have a stock solution of 14.8 MNH3. How many millilitres of this solution should you dilute to make 1000.0 ml of 0.250 MNH3? (b) If you take a 10.0-mL portion of the stock solution and dilute it to a total volume of 0.500 L, what will be the concentration of the final solution?

14.7 CATALYSIS - catalyst: substance that changes the speed of a chem rxn w/o undergoing a permanent chem change itself HOMOGENEOUS CATALYSIS - homogeneous catalyst: a catalyst present in the same phase as the reactants in a rxn mixture - the catalyst is there at the start of the rxn, whereas the intermediate is formed during the course of the rxn - catalyst may affect the rxn rate by ~ altering Eaor A ~ by providing a new mechanism for the rxn that has an E vaaue lower than the E valae for uncatalyzed rxn, OR assist in the orientation of reactants & so incr A HETEROGENEOUS CATALYSIS - heterogeneous catalyst: exists in a phase different from the phase of the reactant molecules, usually as a solid in contact with either gaseous reactants or reactants in liq
