a) 64.0 b) 32.0 c) 40.0 d) 80.0 Answer: a Explanation: \[\frac{2}{1}= \sqrt{\frac{M_{x}}{16}} \] Mx = 64

At what temperature, the rate of effusion of \[N_{2}\] would be 1.625 times than that of \[SO_{2}\] at ...

a) 16:1 b) 4:1 c) 1:4 d) 1:16 Answer: b Explanation: \[\frac{r_{1}}{r_{2}}= \sqrt{\frac{d_{2}}{d_{1}}} = \sqrt{\frac{16}{1}} = 4:1\]
