Heat of Reaction per Mole vs Total Heat Measured (q)
Heat of Reaction per Mole
Formula
ΔH_rxn = q / n
Where:
This converts calorimetry data into a molar enthalpy value for the reaction.
Example Calculation
A reaction releases 50 kJ of heat using 0.1 mol of limiting reagent.
- 01ΔH_rxn = q / n
- 02ΔH_rxn = -50 / 0.1
- 03ΔH_rxn = -500 kJ/mol
