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

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
Recycling in a process stream helps in utilising the valuable reactants to the maximum with minimum loss of reactants
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

Stoichiometry
According to Raoult's law, "The vapor pressure exerted by component in a solution is proportional to the mole fraction of that component." Raoult's law is not applicable under the following assumption/condition.

The component molecules are non polar and are of almost equal size
The attractive forces between like and unlike molecules are almost equal
In the formation of solution, chemical combination/molecular association between unlike molecules takes place
No component is concentrated at the surface of the solution
