Ouestions For these questions you are asked that de to give explanations. The explanations should be intelligent, thoughtful explanations s involved in this experiment. One thing to be careful about is that monstrate your understanding of the principle when explaining a phenomenon, you should not just say that Le example, if you add a reactant to an Chatelier's principle says that it would happen. For t if you add the reactant, it will want to reduce it, this is not the reason it converts to product. Just says that mixture, it will co because Le Chatelier would or is there a better explanation?) You need to discuss the effects that the concentrations and whether or not the concentrations will give the appropriate value o nvert it to more product. While Le Chatelier's said it would is not an explanation.

Is the above reaction (from question 2) endothermic or exothermic? Give an explanation based on your results

Explanation / Answer

3) The reaction is exothermic in forward reaction(produces Co(H2O)62+)and endothermic in the reverse reaction.

This is because Co(H2O)62+  Is more stable than CoCl42-(the bonds in the Co(H2O)62+ are stronger than the bonds in CoCl42-)
