At what temperature does the most probable speed (U_mp) of SO2 equal the rms speed (U_rms) of O2 at 300 K?
- 150 K
- 600 K
- 750 K
- 900 K
Correct answer: 900 K
Solution
U_mp(SO2) = sqrt(2RT1/64) and U_rms(O2) = sqrt(3R*300/32). Equating and squaring: 2T1/64 = 3*300/32 → T1 = (3*300*64)/(2*32) = 900 K.
