Enthalpy and Gibbs Free Energy CalculatorIntroduction : the purpose of this calculator is to calculate the value of the enthalphy of a reaction (delta H) or the Gibbs free energy of a reaction (delta G). The form below provides you with blanks to enter the individual enthalpies or free energy d ata points for a given reaction. Once entered, simply click on the "Evaluate" button to compute the appropriate value.
Note: if you do not have a second or third reactant or product, simply enter the value of "0" in the form.
The form below calculates the reaction enthalphy for:
Keep in mind the following rules:
