Gibbs free energy state function
Webt) Gibbs free energy is a state function. u) The entropy will usually increase when a molecule is broken into two or more smaller molecules. PART II: CONSTRUCTED QUESTIONS (40pts) 1. WebIf the pressure rather than volume is constant, the Gibbs free energy is constant, G(T; p; N) =F(T; V; N)¡pV(5.11) In many applicationsNis not constant but can vary about the mean value,N. IfVis constant, this means a variation in number densityn=N=V.
