You didn't write all of the question. The reaction (only one was written) can't shift unless you do something to it. What did you add or remove?
BTW, you need to inform your prof that the sentence of "By convention, no units are reported for K values" is not necessary. The truth is that K HAS NO UNITS, by convention or otherwise. The numbers that go there are activities and activities have no units so K has no units. It is true that we usually use molarity to avoid calculating activities and since M has units that is often used as units for K but those are "pseudounits" (often called provisional units) since the numbers that should go there don't have units.
1. Write the balanced equation. Use ONLY this equation to reference how the reactions below will shift. Consider whether there is an addition, a removal, or no effect to the reaction.
Co(H2O)6^2+ + 4Cl^- <--> CoCl4^2- + 6H2O
2. Write the equilibrium expression for the reaction. Be sure to consider how water is handled in the equilibrium expression. You may leave off the unit analysis in this case. By convention, no units are reported for K values.
K = [CoCl4^2-] / [Co(H2O)6^2+] [Cl^-]^4
3.Calculate the value of the equilibrium value (K) for the initial flask of CoCl2. (Show your work.)
How do I do this?
