# Problem: As discussed in the “Chemistry Put to Work” box in Section 10.8 in the textbook, enriched uranium can be produced by effusion of gaseous UF6 across a porous membrane. Suppose a process were developed to allow effusion of gaseous uranium atoms, U(g).Compare the ratio of effusion rates for 235U and 238U to the ratio for UF6 given in the essay in the textbook.

🤓 Based on our data, we think this question is relevant for Professor Randles' class at UCF.
