Description Replacement lab: Cobalt Chloride and LeChatlier?s Principle http://chemcollective.org/vlab/85 Click on the words "Cobalt Lab" (on the right side just above WorkBench 1) which will further explain the lab problem within this assignment. After following the directions given there, create a Word document where you will list the following 4 items: Consider the chemical reaction: Co(H 2O) 6 2+(aq) + 4Cl -(aq) <==> CoCl 4 2-(aq) + 6H 2O(l) 1. Predict the effect of removing chloride ions. In which direction will the above reaction shift? 2. Predict the effect of adding HCl. In which direction will the above reaction shift? 3. Is the reaction endothermic or exothermic? 4. The environmental temperature for this lab is 25 oC. Calculate the K value at this temperature as well as the K value at any other temperature of your choosing between 0 and 100 0C. Report this new K value and at what temperature it was found. Hint: You can compare these two K values to help verify your determination of endothermic or exothermic for the above reaction. Submit the Word document
