WebSo the Gibbs phase rule allows us to predict how many degrees of freedom we have for a certain number of phases and a certain number of components. For the three cases above (water, ice/water and two miscible liquids) we see that it works. Water at 25 C has one phase and one component, so F = 2. Ice/water has 2 phases and one component, so F = 1. WebCombining these two arguments, we get the non-reactive Gibbs Phase Rule that the number of degrees of freedom, D is: D = (2 +N −)−(N −N) =2 +N − If we now include a number of reactions ( r ), each must satisfy an equilibrium expression, so For each j of the r reactions we can write Kj = i fifio ij http://pillars.che.pitt.edu/student/slide.cgi?course_id=19&slide_id=101.0 ready math free printable worksheets
