a)    What are the molecules and ions doingin solution – are they static or moving around? 

b)   Can ions or molecules that are isolatedfrom one another react? What must happen for them to react? 

c)    Why should the permanganate disappearfaster if the concentration of H3O+(aq) is higher? 

d)   Devise a general, qualitative, statementabout the effect that an increase in the concentration of areactant has on the rate of a reaction, and an explanation of thateffect.
