Respuesta :

There will be variances between isotopes, however by ignoring these and using the avg mol wt of N2 = 28 and Xe = 132; Rate(N2)/Rate(Xe) = sqrt (132/28) = 2.17

What  an isotope is instead ?

Isotopes are atoms with the same quantity of protons but differing numbers of neutrons. They differ in mass, which affects their physical characteristics even if they have nearly identical chemical makeup.

What makes anything an isotope?

There are three known one-proton nuclei that have 0 neutrons, 1 neutrons, and 2 neutrons, respectfully. They are known as hydrogen isotopes (first from Greek isos, which means "same," and topos, which means "place") since they all occupy the same location in the periodic chart that is designated for atomic number 1.
