Which is a postulate of the kinetic-molecular theory?
Sever21 [200]
  • A gas is composed of a large number of particles called molecules (whether monatomic or polyatomic) that are in constant random motion.
  • Because the distance between gas molecules is much greater than the size of the molecules, the volume of the molecules is negligible.
  • Intermolecular interactions, whether repulsive or attractive, are so weak that they are also negligible.
  • Gas molecules collide with one another and with the walls of the container, but these collisions are perfectly elastic; that is, they do not change the average kinetic energy of the molecules.
  • The average kinetic energy of the molecules of any gas depends on only the temperature, and at a given temperature, all gaseous molecules have exactly the same average kinetic energy.

Which of the following would you predict to have a positive value for º ?
alexdok [17]
Given:

AgCl (s) ===> Ag+ (aq) + Cl- (aq)
- negative entropy

H2O(g) ===> H2O(l)
- positive entropy

2Na (s) + Cl2 (g) ===> 2NaCl (s)
- positive entropy

Br2(l) ===> Br2 (s)
-positive entropy

They are identified to have positive or negative values of entropy based on the phases of the reactants and products.
