Stoichiometry
Heat of reaction is not influenced by

The route/method through which final products are obtained

None of these

Whether the reaction is carried out at constant temperature or constant pressure

The physical state (e.g., solid, liquid or gaseous) of reactants and products

Stoichiometry
Pick out the wrong unit conversion of calorific value.

1 BTU/ft³ = 8.9 kcal/m³ = 0.038 MJ/m³

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

1 kcal/m³ = 0.1124 BTU/ft³

1 BTU/lb = 2.3 kcal/kg

1 BTU/ft³ = 8.9 kcal/m³ = 0.038 MJ/m³

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

1 kcal/m³ = 0.1124 BTU/ft³

1 BTU/lb = 2.3 kcal/kg
