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 wrong. N₂ and O₂ are different elements with different molar masses.
b. is wrong. 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).
