5. Given the two reactions: Reaction 1:Zn(s)+S(s)ZnS(s) Reaction II: 1Pb(NO3)2(aq)+2KI(aq)1PbI2(s)+2KNO3(aq) a. Reaction 1 is faster than reaction Il because reaction II has more moles of particles that must collide to produce an activated complex. b. If we increase the surface area of both solids in Reaction I, then the rate of reaction will increase significantly. c. Reaction I is slower than reaction II. d. We could monitor the rate of reaction I by measuring the change in mass over time. 6. Given: Heat +2BaCrO4(s)+2H(aq)+1H2O(b)+2Ba(aq)2++1Cr2O72(aq) BaCrO4(aq) is yellow and Cr2O72(aq) is orange. a. Entropy decreases in the reverse direction. b. The reaction is endothermic in the forward direction. c. The rate at which the yellow barium chromate is consumed equals the rate at which barium ions are produced. d. An equilibrium solution will contain equal moles of hydrogen ions and barium ions. e. An increase in temperature will make the solution more orange. f. Decreasing the volume of the reaction vessel will cause a shift to the left. g. Adding more water to the equilibrium system will cause the system to shift left. h. Adding a catalyst will not affect the position of the equilibrium
