Problem

Three aqueous reactions are listed below. Coefficients are placed to make each chemical equation stoichiometrically correct. 1. H2SO4(aq)+2 NaOH(aq)→Na2SO4(aq)+2 H2O(l)H_2SO_4(aq) + 2\,NaOH(aq) \rightarrow Na_2SO_4(aq) + 2\,H_2O(l) 2. 2 KI(aq)+Pb(NO3)2(aq)→2 KNO3(aq)+PbI2(s)2\,KI(aq) + Pb(NO_3)_2(aq) \rightarrow 2\,KNO_3(aq) + PbI_2(s) 3. Zn(s)+Cu2+(aq)→Zn2+(aq)+Cu(s)Zn(s) + Cu^{2+}(aq) \rightarrow Zn^{2+}(aq) + Cu(s) For each reaction, consider the particulate-level changes that occur in solution and the macroscopic evidence that accompanies the process. (a) Classify reaction 1 by its dominant reaction class. Justify your classification by explicitly identifying the species exchanged and the major driving force that shifts the equilibrium toward products. (b) Classify reaction 2 by its dominant reaction class. Justify your classification by explicitly identifying the species exchanged and the major driving force that shifts the equilibrium toward products. (c) Classify reaction 3 by its dominant reaction class. Justify your classification by explicitly identifying the species exchanged and the major driving force that shifts the equilibrium toward products.
