tration of Cl . The half-life of Tc, a radioisotope commoealy used in the reaction rate? nuclear medicine, is about 6 hours. How much of a crease the rate by a factor of eight ave the rate unchanged uble the rate Ive the rate 5.0 pg sample remains after 2 days? (A) 002g(B) 06pg (C) 08HB (D) 3 ug Which compound has the highest molar solubility in a 50. of consumption of C,H, is 0.45 M-s. What is of production of H:O 2NH3 + 302 â 2CH2CHCN + 61120 neutral solution? (A) Ag, K,"85s 10-17 (B) Baco K 2.6 10 (C) Fe(OH. K-2.810 (D) Zus, K.-3x1023 (B) 0.45 Ms (D) 2.70 Ms 5 M-s 51. Which will change the value of K, for silver szide, Ag,? (A) Adding water to the solution (B) Adding silver ions to the solution. (C) Removing azide ions from the solution. (D) Increasing the temperature of the solution. nergy diagram best matches an exothermic with this mechanism? E+S ES (Fast) ES E+P (Slow) 52. If solid Na PO4 is added to a saturated aqueous solution of Ca(POs): what will happen to the concentration of Ca" in solution? (A) It will decrease. (B) It will increase. (C) It will be unchanged. (D) It will become equal to the PO Reaction Progress â Reaction progress â concentration. A solution contains 0.002 M Pb and 0.002 M Ag'. What happens PbCI when NaCKs) is added to bring AgCI 53. 1.2x10 1.810 the chloride ion concentration to 0.01 M? â (A) Neither Pbc, nor AgCI precipitate. (B) Both PtCl, and AgCl precipitate. (C) PbCl, selectively precipitates. Reaction Progress . Reaction Progress â Y) ows (D) AgCI selectively precipitates. 54. For Agl, the Kp value is 8.5x10'1" and for [Ag CN)l the two ies. ed Ke value is 1.0x10. Which statement is true? (A) Agl is completely insoluble in a solution that contains CN contains CN contains CN time (min) (B) Agl is less soluble in water than in a solution that (C) Agl is more soluble in water than in a solution that (D) Agl is equally soluble in water and in a solution that nstant is consistent with the data?
