Regents Chemistry Practice Problems : GASES

Kinetic molecular theory has the following statements which need to be memorized:

1. Collisions of gas particles may transfer energy from one particle to another, but the total kinetic energy remains the same.
2. Gas particles have negligible volume.
3. The gas particles are in continuous random motion and move in straight lines.
4. No forces of attraction or repulsion are considered to exist between the particles.
   Choice 2 is the correct answer

STP stands for standard temperature and pressure. When temperature, pressure, and volume (1L) is equal for two gases, the number of moles and atoms are equal as well. This is due to the ideal gas law (PV=nRT). Choice 2 is the correct answer

Real gas behaves most like an ideal gas under low pressure and high temperature. Choice 3 is the correct answer.

2. Collisions of gas particles may transfer energy from one particle to another, but the total kinetic energy remains the same.
3. Gas particles have negligible volume.
4. The gas particles are in continuous random motion and move in straight lines.
   Choice 2 is the correct answer choice.

In order for a reaction to occur, reactants must have proper orientation and enough energy. Choice 2 is the correct answer choice.

When temperature, pressure, and volume is equal for two gases, the number of moles and atoms are equal as well. This is due to the ideal gas law (PV=nRT). Choice 2 is the correct answer choice because it lists the same pressure, temperature and volume as given in the question.

Noble gases are located in Group 18 on the Periodic Table. A noble gas consists of one element, eliminating choices 3 and 4. Noble gas are not diatomic (two atoms together), eliminating choice 1. Answer choice 2 is the correct answer.
