Which of the following would the kinetic theory address

The Kinetic Theory of gases states that the gases are made of small particles (atoms or molecules) which are in random motion.

Postulates of Kinetic Molecular Theory of gases:

1. All gases are made up of a large number of minute particles of molecules.

2. The molecules are separated from one another by large distances, called as intermolecular spaces.

3. The molecules are in the state of rapid motion in all directions. They collide with each other and the walls of the container, and thus change their directions.

4. There is no loss of energy when the molecules collide among themselves and the wall of the container.

5. The molecules are independent of each other as the molecules has no forces of interaction (repulsive or attractive) between molecules.

6. The pressure exerted by the gas is due to the collision of the molecules with the walls of the container per unit area.

7. The average Kinetic energy of the gas molecules is directly propotional to the absolute temperature.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
