Assuming that in free-radical polymerization the rate constants can be replaced by the appropriate Arrhenius expressions: kd = Adexp(-Ed/RT) kp = Apexp(-Ep/RT)
Substituents on an aromatic ring can have several effects on electrophilic aromatic substitution reactions. Substituents can activate or deactivate the ring to substitution
Problem- What is the proton concentration in a solution of 102.7 mM acetic acid (this concentration represents the sum of both the acetic acid and the deprotonated acetate) at pH 5.77 if the pKa of acetic acid is 4.76?
Show that you can selectively precipitate ONLY AgBr at a concentration of Ag of 5.5x10^-10 M in a solution that contains both Br- and CI- at a concentration of 0.02M.
