How does the Thermochem Calculator work?

Input reaction and temperature Then: Calculate ΔH from bond energies or Hess's law Then: Determine spontaneity: ΔG = ΔH - TΔS.

Can you give an example of how to use the Thermochem Calculator?

Example: Input Combustion: exothermic (ΔH 0) gives a result of Spontaneous at all temperatures (ΔG < 0).

Is the Thermochem Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
