Stoichiometry
Pick out the wrong statement about the recycle stream in a process.

The ratio of the quantity of a reactant present in the reactor feed of a recycling operation to the quantity of the same reactant entering the process as fresh feed is called combined feed ratio
Recycling in a process stream helps in utilising the valuable reactants to the maximum with minimum loss of reactants
Recycling is exemplified by refluxing back a part of the distillate to the distillation column to maintain the quantity of liquid within the column
Recycling in a process does not help in getting higher extent of reaction
