The above given is a displacement reaction
In which one metal relocates
other metal couple change in their electrode chemical potential occurs
if you liken the electrode potential values it will tell the
reaction type
The featoms has affinity to lose electron and it get transformed into ions where as copper has
tendency to get reduced and converted to copper metal a as result we will see brown ppt which is nothing but
copper metal
Fe-0.044 -ve shows inclination to lose electron
Cu+0.34 + ve indicates tendency to gain electron
in these case
hope it helps
