Question

The ratio of rms velocity of h2 at 100k and that of o2 at 400k is

Answer 1

Answer:

c1/c2 = 1.414

Explanation:

RMS velocity, c = √(3RT/Mo)

where Mo is the molecular mass

For H2,

T1 = 100K

Mo1 = 2

For O2,

T2 = 400K

Mo2 = 16

c1/c2 = √(3RT1/Mo1) / √(3RT2/Mo2)

c1/c2 = √(T1×Mo2 / T2×Mo1)

c1/c2 = √(100×16/400×2)

c1/c2 = √2 = 1.414

I hope this helps:)
