The 1st Law of Thermodynamics in Chemical Reactions | I. A. Stepanov
; | Date: |
10 Nov 2000 | Subject: | General Physics; Chemical Physics | physics.gen-ph physics.chem-ph | Affiliation: | University of Latvia, Riga, Latvia | Abstract: | In the previous papers of the author it has been shown that the 1st law of thermodynamics in chemical reactions is the following one: dU=dQ+PdV+SUM In the present paper this theory was developed and it has been shown that the 1st law of thermodynamics in chemical reactions has the following form: dC=-dU+dA and -dU=dQ where dC is the change in the chemical energy, dU is the change in the internal energy. Internal energy is the energy of thermal motion of molecules. | Source: | arXiv, physics/0011021 | Services: | Forum | Review | PDF | Favorites |
