WebFeb 24, 2024 · As a result, we usually calculate the change in enthalpy. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change. In the laboratory, calorimetry techniques are used to measure enthalpy change. Enthalpy change is defined as the heat change at constant pressure, which is … WebMar 24, 2024 · The heat of reaction is the enthalpy change for a chemical reaction. In the case above, the heat of reaction is − 890.4kJ. The thermochemical reaction can also be written in this way: CH 4(g) + 2O 2(g) → CO 2(g) + 2H 2O(l) ΔH = − 890.4kJ. Heats of reaction are typically measured in kilojoules.
