CHEM 112 Lecture Notes - Lecture 11: Lead
Document Summary
Remember: pure liquids and solids will not appear in keq equations - only aqueous and gaseous molecules. Caco3 (s) cao (s) + co2 (g: autopilot first. Keq = [co2][cao]/[caco3: remove solids and liquids. Pb2+ (aq) + 2cl- (aq) pbcl2 (s: autopilot first. Keq = [pbcl2]/[pb2+][cl-]2: remove solids and liquids. Ch3cooh (aq) + h2o (l) ch3coo- (aq) + h3o+ (aq: autopilot first. Keq = [h3o+][ch3coo-]/[ch3cooh][h2o: remove solids and liquids. 3- (aq) + 3sr2+ (aq) sr3(po4)2 (s: autopilot first. Given generic formulae, we can determine how inverse reactions or reactions with the same products/reactions are related. We will assume that there are no pure solids or liquids in any of the following equations: a c. Keq2 = [d]/[b: a + b c + d keq3 = keq1 * keq2 = [c][d]/[a][b: c + d a + b keq4 = 1/keq3. [a][b]/[c][d: 2a + 2b 2c + 2d.
