Consider an experiment where the two gas phase reactants are held at room temperature in separate flasks. The flasks are connected by a narrow tube with valves to control when the gases mix. When the gases meet, they form a solid according to the following reaction: NH3(g) + BF3(g) → NH3BF3(s) BF3 NH3 A B a) If the valves were opened simultaneously and the gases reacted, predict approximately where in the tube would the solid form. Indicate the letter (A, B, C, or D) of the approximate location in the exam text box. Show your supporting work in your uploaded work. b) Assuming the temperature remains constant throughout the reaction, what happens to the pressure inside the apparatus after the valves open? Indicate increases, decreases, or remains the same in the exam text box. Explain your reasoning in your uploaded work.
Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
