At what temperature, the rms velocity of SO_(2) be same as that of O_(

1.	At what temperature, the rms velocity of SO_(2) be same as that of O_(2) at 303K ?
Answer» 273 K 606 K 303 K 403 K Solution :(b) `(U_(rms)(SO_(2)))/(U_(rms)(O_(2)))=SQRT((T(SO_(2)))/(M(SO_(2)))XX(M(O_(2)))/(T(O_(2))))` i.e. `1=sqrt((T(SO_(2)))/(64)xx(32)/(303))or T(SO_(2))=606 K`
