GENERAL earlier concepts from CH301 and Exam 1 302 are used in but not examined directly: DON'T FORGET YOUR NON-PROGRAMMABLE CALCULATOR... Chapter 6: (6.6-6.8) Calculations*: Be able to do all types covered in class; setting up ICE tables and writing Kpor Kcexpressions for any given equation as needed to help you. Again, WATCH the stoichiometric coefficients and state symbols. I will try to indicate which if it is unclear but generally as for exam 1, if you are given moles and a container volume it is probably Kcthat you are suing or calculating. Remember if you are working with Kc, then all values in the ICE tables should be in units of molarity. Watch to see what the question wants at the end, moles or molarity, change or equilibrium value, and of which component! Le Chatalier's Principle: be able to predict which way the reaction will shift given an applied stress, set up an ICE table if needed. Remember, calculate Q and compare it to K ( you might have to calculate that too so read the Q carefully) to tell you which way the reaction will shift, if its not obvious. Just think about the idea that the system is trying to get back to a point where Q is equal to K. Then set up your ICE table and
