Consider the following reaction:
Cu(s) +2 AgNO3(aq)= Cu(NO3)2(aq) +2 Ag(s)
In a rate experiment, a coil of copper wire is placed into a solution of silver nitrate. The
following data are recorded.
Time (hours): 0.0
Mass of Copper (g): 3.45
and
Time (hours): 4.0
Mass of Copper (g): 2.12
Calculate the rate of this reaction. (reaction rate= change in amount over change in time)
