Sonntag, Borgnakke and van Wylen Concept-Study Guide Problems 15.1 Is the concept of equilibrium limited to thermodynamics? Equilibrium is a condition in which the driving forces present are balanced, with no tendency for a change to occur spontaneously. This concept applies to many diverse fields of study – one no doubt familiar to the student being that of mechanical equilibrium in statics, or engineering mechanics. 15.2 How does Gibbs function vary with quality as you move from liquid to vapor? There is no change in Gibbs function between liquid and vapor. For equilibrium we have g g = g f . 15.3 How is a chemical equilibrium process different from a combustion process? Chemical equilibrium occurs at a given state, T and P, following a chemical reaction process, possibly a combustion followed by one or more dissociation reactions within the combustion products. Whereas the combustion is a one-way process (irreversible) the chemical equilibrium is a reversible process that can proceed in both directions. 15.4 Must P and T be held fixed to obtain chemical equilibrium? No, but we commonly evaluate the condition of chemical equilibrium at a state corresponding to a given temperature and pressure. 15.5 The change in Gibbs function for a reaction is a function of which property? The change in Gibbs function for a reaction is a function of T and P. The change in standard-state Gibbs function is a function only of T.
Sonntag, Borgnakke and van Wylen 15.6 In a steady flow burner T is not controlled, which properties are? The pressure tends to be constant, only minor pressure changes due to acceleration of the products as density decreases velocity must increase to have the same mass flow rate.
