Document Summary
Ratio of products and reactants will be given by the mass action expression : (cid:8869) k=fa% tea. * le chateller "s principle states that for any system not at equilibrium, there is a thermodynamic driving force that favors reestablishing the equilibrium state. Chemical standard state defined by : (cid:8869) pressure = i bar. 273. 15 k (cid:8869) t - (cid:8869) solutes at concentrations of l h each. Free energy of any component of the system increases from its standard value with a logarithmic dependence on its activity. Sg represents the standard state free energy for the reaction (cid:8869) represents the driving force from a reference state toward the equilibrium state. S g = ago + rt in q. * the free energy change in a chemical reaction depends on the standard state free energy change ( ago) and on the concentrations of reactants and products (described by rt in q )
