Stoichiometry
Pick out the wrong unit conversion of thermal conductivity.

1 BTU/ft².hr.°F/inch = 1.488 kcal/m². hr.°C/m

1 kcal/m.hr.°C = 0.672 BTU/ft.hr.°F = 1.163 W/m. °K

1 BTU/ft².hr.°F/ft = 1.488 kcal/m². hr.°C/m

1 W/cm.°C = 85.985 kcal/m.hr.°C = 57.779 BTU/ft.hr.°F

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

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

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 does not help in getting higher extent of reaction
