Question:

One way of separating oxygen isotopes is by gaseous dif-fusion of carbon monoxide. The gaseous diffusion process behaves like an effusion process. Calculate the relative rates of effusion of ¹²C₁₆O, ¹²C₁₇O, and ¹²C₁₈O. List some advantages and disadvantages of separating oxygen isotopes by gaseous diffusion of carbon dioxide in-stead of carbon monoxide.
