Molar Enthalpy Change Calculator

Molar Enthalpy Change (ΔH)

• \(ΔH\) = Molar enthalpy change (kJ/mol)
• \(q\) = Heat energy absorbed/released (J)
• \(n\) = Amount of substance (moles)

Example: If 2500J of heat is released by 0.05 moles of reactant:
\[ \Delta H = \frac{-2500\, \text{J}}{0.05\, \text{mol}} = -50\, \text{kJ/mol} \]
