please help with question four and five
3. For the reaction PbCl2 (6) Pb2+ + 2CV, what is the value of the equilibrium constant if [Pb 2+] = 0.0022 M and (CI) is 0.027 M? [P621] = 0.002am kc [Pb2+] [...] [cr] =0.027m [PbCl2 (s) [pbela (s)]= Ke=0.0022x10.02222 4. The equilibrium constant for the reaction of nitrogen and hydrogen to produce ammonia is = 1.6.x10-6 0.094 M? at 450°C. If [N2) =0,012 M and [H2] = 0.42 M at equilibrium,...

Chateler's principle
In the chart below: • Indicate the color of each solution as darker or lighter than the control after the addition of the specified substance. • Indicate the direction the equilibrium shifted as "toward products" or "toward reactants" based on the color change. • Based on the direction of the shift, indicate the substance(s) that increased which will either be the two reactants present on the reactant side of the equilibrium equation or the complex present on...
