For each reaction, identify the acid-base conjugate pairs. Then rank all reacionts in order of increasing tendency for the reaction to go to completion (to the right). (Hint: reactions runs toward weaker acid and base).
a) CH3COO- + HCN <--> CH3COOH + CN^-
b) CH3OH + Br^- <--> CH3O^- + HBr
c) HSO4^- + NH3 <--> SO4^2- + NH4^+
d) HClO4 + CH3NH2 <--> ClO4^- + CH3NH3^+
