1-The equilibrium constant for the hypothetical reaction 2 C(aq) â D(aq) + E(aq) is 3.0x10-3 at 25 °C. At a particular moment, [C]=[D]=[E]=5.0x10-4 M. In which direction, if any, will the reaction proceed?
2-You will be diluting several solutions this week. If 5.00 mL of a 1.25 M solution is diluted to 25.0 mL, what is the final molarity of the dilute solution?
3- Look up the safety data sheet for nitric acid here. Other than being a strong acid, what characteristic makes HNO3 hazardous? Hint: look for information on stability and reactivity.

4- The equilibrium constant for the reaction Co2+(aq) + 4 SCN-(aq) â [Co(SCN)4]2-(aq) is 1.5x103. What is the ratio of bound Co2+ to free Co2+ if the equilibrium [SCN-] is 0.20 M?
5- All chemical reactions can proceed in both the forward and reverse directions. What does it mean when a reaction reaches dynamic equilibrium? Did your reactions reach dynamic equilibrium today?
