Draw a reaction free-energy diagram for a reaction AHBHC that meets the following criteria: The standard free energies are in the order C , A , B, and the rate- limiting step of the reaction is BHC.
1. Which cations (and which anions) are in very INSOLUBLE IONIC compounds 2– + 2+ 2+ 2+ - S (e2–ep.: compounds of NH , the 4lka+i metal cations, Ca , Sr , Ba ) - CO 3 (excep.: compounds of NH , th4 alkali metal cations) - PO 43–(excep,: “ “) – + 2+ 2+ 2+ - OH (excep.: compounds of NH , the a4kali metal cations, Ca , Sr , Ba ) 167 2. How are solubility guidelines used to predict whether a precipitate forms in an exchange reaction - Precip rxns occur when pairs of opp charged ions attract each other so strongly that they form an insoluble ionic solid - to predict whether precip forms, 1) not
