Consider the following reaction involving 1.0g of powdered zinc. The rates, in order of fastest to slowest, are
Zn(s) + 2 HCl (aq) -> ZnCl2(aq) + H2(g)
A 2, 1, 3
B 3, 2, 1
C 1, 2, 3
D 3, 1, 2
basically, i dont understand the question.

If that's all, there is no question here. Nothing else? Some plot? List of solutions? Looks like 1, 2 and 3 refer to some data you have not listed.

No idea. Perhaps sets of temperature/pressure conditions, acid concentrations, zinc granulation.
