Pick out the wrong unit conversion of calorific value.

Stoichiometry
Pick out the wrong unit conversion of calorific value.

1 BTU/lb = 2.3 kcal/kg

1 BTU/ft³ = 8.9 kcal/m³ = 0.038 MJ/m³

1 kcal/m³ = 0.1124 BTU/ft³

1 kcal/kg = 1.8 BTU/lb = 4.186 kJ/kg

1 BTU/lb = 2.3 kcal/kg

1 BTU/ft³ = 8.9 kcal/m³ = 0.038 MJ/m³

1 kcal/m³ = 0.1124 BTU/ft³

1 kcal/kg = 1.8 BTU/lb = 4.186 kJ/kg

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

Recycling in a process does not help in getting higher extent of reaction

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