Propose a mechanism for the conversion of the E isomer of geranyl pyrophosphate to the Z

Week 6, Chem 143, Prof. Cracolice Chapter 54: How is pH of a Weak Acid Determined 2/29/16 54.1 How is the K aValue for a Weak Acid Determined  Percentage of ionization­ ratio a part to the whole multiplied 100%  Strong acid 100% ionizes  Weak acid­ has ionization percentage as less than 100%  Using Ice tables and equations an K a  pH will give you amount of hydronium in solution at equilibrium  take amount of reactant at equilibrium and divid by original amount to get percentage ionization  make sure to watch sig figs  always check to see if you have correct number of sig figs  when give percentage ionization =change row on the ice table  becomes x% of initial concentration  possible to have negligi
