Ranking Activity from Experimental Results: $Ag, Au, Sn$

CHEM-M$OXSC

In a laboratory experiment, you run the following reactions and obtain the corresponding results.

$$\textrm{Sn} + 2\textrm{AgNO}_3 \rightarrow \textrm{Sn(NO}_3\textrm{)}_2 + 2\textrm{Ag}$$
$$3\textrm{Sn} + 2\textrm{AuCl}_3 \rightarrow 3\textrm{SnCl}_2 + 2\textrm{Au}$$
$$3\textrm{Au} + \textrm{AgNO}_3 \rightarrow \textrm{No reaction}$$

Rank the activity (the strength as reducing agents) of the elements $\textrm{Ag}$, $\textrm{Au}$, and $\textrm{Sn}$, given the following observed reactivity information.

A

$Ag > Au > Sn$

B

$Au > Ag > Sn$

C

$Au > Sn > Ag$

D

$Sn > Ag > Au$

E

$Sn > Au > Ag $
