Presentation Transcript

  1. Free energy change

  2. Add species to the Basis pane in Rxn to write a balanced reaction. Constrain the activity of species in the reaction. Assume mmol/kg levels of bicarbonate, μmol/kg levels of acetate and methane. Set temperature

  3. Move to the Results pane. If the reaction is constrained such that the reactants or products are favored thermodynamically, Rxnwill calculate the free energy change of reaction. For the dismutation of acetate at 25 °C, there is a modest thermodynamic drive for the reaction to proceed forward.
