D) It is unlikely that a specific cause can be determined, but the treatment would likely be the same in either case
Answer:
c. The average kinetic energies of the two gases are the same.
Step-by-step explanation:
A major postulate of the Kinetic Molecular Theory is that the average kinetic energies of all gases are the same at the same temperature.
a. is <em>wrong</em>. N₂ and O₂ are different elements with different molar masses.
b. is <em>wrong</em>. According to Avogadro's Law, the partial pressure varies directly as the number of moles. There are twice as many molecules of O₂ as of N₂, so p(O₂) = 2p(N₂).
Answer:
A is the answer. The others would be examples of endothermic.
