Is the reaction between Cu and Fe2(SO4)3 possible ? If no okay but if yes then why as copper is less reactive than iron it must not react with it at all. Please help

@ pritesh 
yes, the reaction is possible , if u have added excess amount of cu . otherwise not . 
beacuse if u have added excess amount of cu , then the reaction will be a double displacement reaction . 
and the product will be formed as cuso4+fe2+ 
, yes copper is less reactive than iron but excess amount of cupper will displace ion from the solution .. 
HOPE IT CLEARS YOUR DOUBT ..
