Unformatted text preview: Atkins & de Paula: Atkins Physical Chemistry 8e Checklist of key ideas Chapter 5: Simple Mixtures Chapter 5: Simple Mixtures THE THERMODYNAMIC DESCRIPTION OF MIXTURES 5.1 Partial molar quantities partial molar volume, the change in volume per mole of A added to a large volume of the mixture; V J = ( V / n J ) p,T,n . total volume of a binary mixture, V = n A V A + n B V B . partial molar Gibbs energy and the definition of the chemical potential, J = ( G / n J ) p,T,n . total Gibbs energy of a binary mixture, G = n A A + n B B . fundamental equation of chemical thermodynamics d G = V d p T d S + A d n A + B d n B + . Chapter 5: Simple Mixtures chemical potential in terms of U , J = ( U / n J ) S,V,n . in terms of H , J = ( H / n J ) S,p,n . in terms of A , J = ( A / n J ) T,V,n . GibbsDuhem equation, J n J d J = 0. 5.2 The thermodynamics of mixing standard chemical potential of a perfect gas, o , the chemical potential of the pure gas at 1 bar. 5.1 Partial molar quantities (cont..) Chapter 5: Simple Mixtures chemical potential of a perfect gas, = o + RT ln( p / p o ). Gibbs energy of mixing of two perfect gases, mix G = nRT ( x A ln x A + x B ln x B ). entropy of mixing of two perfect gases, mix S = nR ( x A ln x A + x B ln x B )....
