23In mathematical terms: y = mx + bV = mn + bAvogadro’s Law
24Avogadro’s Hypothesis At constant temperature and pressure, equal volumes of gases contain equal number of particles
253. Hydrogen gas [8. 3 liters] reacts in the presence of 2 3. Hydrogen gas [8.3 liters] reacts in the presence of 2.5 liters of nitrogen gas at 370C and 100 kPa. What volume of ammonia is produced at these same conditions?
28Kinetic Molecular Theory 1. Gases consist of small particles that are far apart in comparison to their own size. These particles are considered to be tiny points occupying a negligible volume compared to that of their container.
29Kinetic Molecular Theory 2. Molecules are in rapid and random straight-line motion. This motion can be described by well-defined and established laws of motion.
30Kinetic Molecular Theory 3. The collisions of molecules with the walls of a container or with other molecules are perfectly elastic. That is, no loss of energy occurs.
31Kinetic Molecular Theory 4. There are no attractive forces between molecules or between molecules and the walls with which they collide.
32Kinetic Molecular Theory 5. At any particular instant, the molecules in a given sample of gas do not all possess the same amount of energy.
